Supongamos que tenemos un cierto DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.uniform(-5, 6, (5, 5)), columns = list("ABCDE"))
df
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0002.jpg"></a>
El método <em>.style.applymap()</em> aplica una función a los valores del DataFrame. Esta función deberá aceptar como argumento un escalar (cada uno de los valores del DataFrame) y deberá devolver una cadena de texto con la pareja CSS "atributo-valor".
Por ejemplo, veamos la siguiente función:
def color_negative_red(val):
color = 'red' if val < 0 else 'black'
return 'color: %s' % color
Si el valor recibido es negativo la variable "<em>color</em>" tomará el valor "<em>red</em>". En caso contrario tomará el valor "<em>black</em>". La función devuelve el texto "<em>color: xxxx</em>", siendo "<em>xxxx</em>" el texto con el color en cuestión.
Probémosla con un valor:
color_negative_red(-4)
'color: red'
Ahora basta con ejecutar el método mencionado de nuestro DataFrame, <em>.style.applymap()</em>, pasando como argumento la función anterior:
df.style.applymap(color_negative_red)

def text_format(val):
color = 'salmon' if val < 0 else 'white'
return 'background-color: %s' % color
Nuevamente, si probamos la función...

Supongamos que tenemos un cierto DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.uniform(-5, 6, (5, 5)), columns = list("ABCDE"))
df
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0002.jpg"></a>
El método <em>.style.applymap()</em> aplica una función a los valores del DataFrame. Esta función deberá aceptar como argumento un escalar (cada uno de los valores del DataFrame) y deberá devolver una cadena de texto con la pareja CSS "atributo-valor".
Por ejemplo, veamos la siguiente función:
def color_negative_red(val):
color = 'red' if val < 0 else 'black'
return 'color: %s' % color
Si el valor recibido es negativo la variable "<em>color</em>" tomará el valor "<em>red</em>". En caso contrario tomará el valor "<em>black</em>". La función devuelve el texto "<em>color: xxxx</em>", siendo "<em>xxxx</em>" el texto con el color en cuestión.
Probémosla con un valor:
color_negative_red(-4)
'color: red'
Ahora basta con ejecutar el método mencionado de nuestro DataFrame, <em>.style.applymap()</em>, pasando como argumento la función anterior:
df.style.applymap(color_negative_red)
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0003.jpg"></a>
El resultado es el DataFrame tras aplicar el formato en cuestión a cada uno de sus valores:
Esto es aplicable con otras propiedades gráficas. Por ejemplo, si deseamos modificar el color de fondo de las celdas del DataFrame de forma que se muestren rojizas para los valores negativos (color "<em>salmon</em>" en el siguiente código) y blancas para los no negativos, podríamos usar la siguiente función:
def text_format(val):
color = 'salmon' if val < 0 else 'white'
return 'background-color: %s' % color
Nuevamente, si probamos la función...
text_format(-2)
'background-color: salmon'
...comprobamos que se devuelve una propiedad CSS y su valor en formato de texto. Apliquemos nuestra función al DataFrame:

Drupal\editor\Plugin\Filter\EditorFileReference->process('Es posible modificar el formato de los valores mostrados en un DataFrame pandas usando las <a href="https://pandas.pydata.org/pandas-docs/stable/user_guide/style.html">herramientas de estilo</a> de esta librería.
Supongamos que tenemos un cierto DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.uniform(-5, 6, (5, 5)), columns = list("ABCDE"))
df
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0002.jpg"></a>
El método <em>.style.applymap()</em> aplica una función a los valores del DataFrame. Esta función deberá aceptar como argumento un escalar (cada uno de los valores del DataFrame) y deberá devolver una cadena de texto con la pareja CSS "atributo-valor".
Por ejemplo, veamos la siguiente función:
def color_negative_red(val):
color = 'red' if val < 0 else 'black'
return 'color: %s' % color
Si el valor recibido es negativo la variable "<em>color</em>" tomará el valor "<em>red</em>". En caso contrario tomará el valor "<em>black</em>". La función devuelve el texto "<em>color: xxxx</em>", siendo "<em>xxxx</em>" el texto con el color en cuestión.
Probémosla con un valor:
color_negative_red(-4)
'color: red'
Ahora basta con ejecutar el método mencionado de nuestro DataFrame, <em>.style.applymap()</em>, pasando como argumento la función anterior:
df.style.applymap(color_negative_red)
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0003.jpg"></a>
El resultado es el DataFrame tras aplicar el formato en cuestión a cada uno de sus valores:
Esto es aplicable con otras propiedades gráficas. Por ejemplo, si deseamos modificar el color de fondo de las celdas del DataFrame de forma que se muestren rojizas para los valores negativos (color "<em>salmon</em>" en el siguiente código) y blancas para los no negativos, podríamos usar la siguiente función:
def text_format(val):
color = 'salmon' if val < 0 else 'white'
return 'background-color: %s' % color
Nuevamente, si probamos la función...
text_format(-2)
'background-color: salmon'
...comprobamos que se devuelve una propiedad CSS y su valor en formato de texto. Apliquemos nuestra función al DataFrame:
df.style.applymap(text_format)

Supongamos que tenemos un cierto DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.uniform(-5, 6, (5, 5)), columns = list("ABCDE"))
df
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0002.jpg"></a>
El método <em>.style.applymap()</em> aplica una función a los valores del DataFrame. Esta función deberá aceptar como argumento un escalar (cada uno de los valores del DataFrame) y deberá devolver una cadena de texto con la pareja CSS "atributo-valor".
Por ejemplo, veamos la siguiente función:
def color_negative_red(val):
color = 'red' if val < 0 else 'black'
return 'color: %s' % color
Si el valor recibido es negativo la variable "<em>color</em>" tomará el valor "<em>red</em>". En caso contrario tomará el valor "<em>black</em>". La función devuelve el texto "<em>color: xxxx</em>", siendo "<em>xxxx</em>" el texto con el color en cuestión.
Probémosla con un valor:
color_negative_red(-4)
'color: red'
Ahora basta con ejecutar el método mencionado de nuestro DataFrame, <em>.style.applymap()</em>, pasando como argumento la función anterior:
df.style.applymap(color_negative_red)
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0003.jpg"></a>
El resultado es el DataFrame tras aplicar el formato en cuestión a cada uno de sus valores:
Esto es aplicable con otras propiedades gráficas. Por ejemplo, si deseamos modificar el color de fondo de las celdas del DataFrame de forma que se muestren rojizas para los valores negativos (color "<em>salmon</em>" en el siguiente código) y blancas para los no negativos, podríamos usar la siguiente función:
def text_format(val):
color = 'salmon' if val < 0 else 'white'
return 'background-color: %s' % color
Nuevamente, si probamos la función...
text_format(-2)
'background-color: salmon'
...comprobamos que se devuelve una propiedad CSS y su valor en formato de texto. Apliquemos nuestra función al DataFrame:

Drupal\editor\Plugin\Filter\EditorFileReference->process('Es posible modificar el formato de los valores mostrados en un DataFrame pandas usando las <a href="https://pandas.pydata.org/pandas-docs/stable/user_guide/style.html">herramientas de estilo</a> de esta librería.
Supongamos que tenemos un cierto DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.uniform(-5, 6, (5, 5)), columns = list("ABCDE"))
df
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0002.jpg"></a>
El método <em>.style.applymap()</em> aplica una función a los valores del DataFrame. Esta función deberá aceptar como argumento un escalar (cada uno de los valores del DataFrame) y deberá devolver una cadena de texto con la pareja CSS "atributo-valor".
Por ejemplo, veamos la siguiente función:
def color_negative_red(val):
color = 'red' if val < 0 else 'black'
return 'color: %s' % color
Si el valor recibido es negativo la variable "<em>color</em>" tomará el valor "<em>red</em>". En caso contrario tomará el valor "<em>black</em>". La función devuelve el texto "<em>color: xxxx</em>", siendo "<em>xxxx</em>" el texto con el color en cuestión.
Probémosla con un valor:
color_negative_red(-4)
'color: red'
Ahora basta con ejecutar el método mencionado de nuestro DataFrame, <em>.style.applymap()</em>, pasando como argumento la función anterior:
df.style.applymap(color_negative_red)
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0003.jpg"></a>
El resultado es el DataFrame tras aplicar el formato en cuestión a cada uno de sus valores:
Esto es aplicable con otras propiedades gráficas. Por ejemplo, si deseamos modificar el color de fondo de las celdas del DataFrame de forma que se muestren rojizas para los valores negativos (color "<em>salmon</em>" en el siguiente código) y blancas para los no negativos, podríamos usar la siguiente función:
def text_format(val):
color = 'salmon' if val < 0 else 'white'
return 'background-color: %s' % color
Nuevamente, si probamos la función...
text_format(-2)
'background-color: salmon'
...comprobamos que se devuelve una propiedad CSS y su valor en formato de texto. Apliquemos nuestra función al DataFrame:
df.style.applymap(text_format)
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-06/python_0004.jpg"></a>', 'es') (Line: 118)

Para ello utilizaremos la función <a href="https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.get_dummies.html" target="_blank">get_dummies</a> de pandas. Comencemos cargando el dataset y examinándolo:
titanic = sns.load_dataset("titanic")
titanic.head()
Veamos los tipos de las características:
titanic.dtypes

pclass int64
sex object
age float64
sibsp int64
parch int64
fare float64
embarked object
class category
who object
adult_male bool

En este dataset, las características categóricas son las correspondientes a los tipos "<em>object</em>" y "<em>category</em>". Extraigamos la lista de estas características usando el método <a href="https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.select_dtypes.html" target="_blank">select_dtypes</a> de pandas:
cat_features = titanic.select_dtypes(include = ["object", "category"]).columns
cat_features
Index(['sex', 'embarked', 'class', 'who', 'deck', 'embark_town', 'alive'], dtype='object')
Ahora podemos pasar a la función pd.get_dummies el subconjunto del dataframe titanic formado por estas características:
cat_titanic = pd.get_dummies(titanic[cat_features], drop_first = True, dummy_na = True)
cat_titanic.head()
Hemos configurado la función con dos argumentos adicionales:
<ul><li><strong>drop_first = True</strong>, que elimina la primera de las columnas generadas para cada característica con el objetivo de evitar la colinealidad (que una de las columnas sea combinación lineal de las demás)</li>
<li><strong>dummy_na = True</strong>, que genera una columna adicional para los valores nulos que se encuentren en cada característica</li>
</ul>Ahora, basta eliminar las características originales:
titanic.drop(cat_features, axis = 1, inplace = True)
...y concatenar el dataframe titanic resultante con el dataframe que hemos generado con las características "dummies":
titanic = pd.concat([titanic, cat_titanic], axis = 1)

Extraigamos la lista de estas características usando el método <a href="https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.select_dtypes.html" target="_blank">select_dtypes</a> de pandas:
cat_features = titanic.select_dtypes(include = ["object", "category"]).columns
cat_features
Index(['sex', 'embarked', 'class', 'who', 'deck', 'embark_town', 'alive'], dtype='object')
Ahora podemos pasar a la función pd.get_dummies el subconjunto del dataframe titanic formado por estas características:
cat_titanic = pd.get_dummies(titanic[cat_features], drop_first = True, dummy_na = True)
cat_titanic.head()
Hemos configurado la función con dos argumentos adicionales:
<ul><li><strong>drop_first = True</strong>, que elimina la primera de las columnas generadas para cada característica con el objetivo de evitar la colinealidad (que una de las columnas sea combinación lineal de las demás)</li>
<li><strong>dummy_na = True</strong>, que genera una columna adicional para los valores nulos que se encuentren en cada característica</li>
</ul>Ahora, basta eliminar las características originales:
titanic.drop(cat_features, axis = 1, inplace = True)
...y concatenar el dataframe titanic resultante con el dataframe que hemos generado con las características "dummies":
titanic = pd.concat([titanic, cat_titanic], axis = 1)

import numpy as np
import seaborn as sns
titanic = sns.load_dataset("titanic")

...y queremos seleccionar las características numéricas. Tenemos varias opciones:
A mano
Obviamente podemos seleccionar éstas manualmente:
seleccion = titanic[["survived", "pclass", "age", "sibsp", "parch", "fare"]]
seleccion.head()
...pero, por supuesto, ésta es la última opción a considerar, pues deseamos llegar a un método "automátivo" que sirva para dataframes de cualquier tamaño.
Con un bucle for
La segunda opción es revisar los tipos de las columnas e ir extrayendo aquellos que nos interesan, que son los que contienen los textos "<em>int</em>" o "<em>float</em>":
features = []
for c in titanic.columns:
t = str(titanic[c].dtype)
if "int" in t or "float" in t:
features.append(c)
features
['survived', 'pclass', 'age', 'sibsp', 'parch', 'fare']
Con el método _get_numeric_data
Otro método es utilizar el método _get_numeric_data:
titanic._get_numeric_data().head()
El problema de este método es que considera las características booleanas como numéricas también.
Con el método select_dtypes
El método <a href="https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.select_dtypes.html" target="_blank">select_dtypes</a> asociado a un dataframe permite extraer (o excluir) las características con cierto tipo. El inconveniente es que resulta necesario incluir todos los posibles tipos en los que estamos interesados:
seleccion = titanic.select_dtypes(include = ["int16", "int32", "int64", "float16", "float32", "float64"])
seleccion.head()
Con el método select_dtypes y "number"
Podemos simplificar el método anterior incluyendo como listado de tipos a incluir la función numpy.number (función que no aparece en la documentación de NumPy) o, simplemente, "<em>number</em>":
seleccion = titanic.select_dtypes(include = ["number"])

Seleccionar aquellas filas en las que campo toma un cierto valor es sencillo. Por ejemplo, para seleccionar aquellas en las que el puerto de embarque es <em>Cherbourg</em> basta hacer lo siguiente:

selection.head()
Si quisiéramos seleccionar las filas en las que el campo en cuestión, <em>embark_town</em>, toma el valor Cherbourg o el valor Queenstown, ya no es tan obvio. La primera opción a la que podemos recurrir es incluir ambas condiciones uniéndolas el operador "o lógico":
selection = titanic[(titanic.embark_town == "Cherbourg") | (titanic.embark_town == "Queenstown")]

El resultado es el esperado siempre que usamos el operador | (el operador <em>or</em> devuelve un error).

Seleccionar aquellas filas en las que campo toma un cierto valor es sencillo. Por ejemplo, para seleccionar aquellas en las que el puerto de embarque es <em>Cherbourg</em> basta hacer lo siguiente:
selection = titanic[titanic.embark_town == "Cherbourg"]
selection.head()
Si quisiéramos seleccionar las filas en las que el campo en cuestión, <em>embark_town</em>, toma el valor Cherbourg o el valor Queenstown, ya no es tan obvio. La primera opción a la que podemos recurrir es incluir ambas condiciones uniéndolas el operador "o lógico":
selection = titanic[(titanic.embark_town == "Cherbourg") | (titanic.embark_town == "Queenstown")]
selection.head()
El resultado es el esperado siempre que usamos el operador | (el operador <em>or</em> devuelve un error).
En todo caso, si la lista de condiciones es larga, la mejor opción es usar el operador de pertenencia <strong>isin</strong> (en el siguiente ejemplo solo se aplica a dos opciones, pero podría ser cualquier número de ellas):

Si quisiéramos seleccionar las filas en las que el campo en cuestión, <em>embark_town</em>, toma el valor Cherbourg o el valor Queenstown, ya no es tan obvio. La primera opción a la que podemos recurrir es incluir ambas condiciones uniéndolas el operador "o lógico":
selection = titanic[(titanic.embark_town == "Cherbourg") | (titanic.embark_town == "Queenstown")]
selection.head()
El resultado es el esperado siempre que usamos el operador | (el operador <em>or</em> devuelve un error).
En todo caso, si la lista de condiciones es larga, la mejor opción es usar el operador de pertenencia <strong>isin</strong> (en el siguiente ejemplo solo se aplica a dos opciones, pero podría ser cualquier número de ellas):
towns = ['Cherbourg', 'Queenstown']
selection = titanic[titanic.embark_town.isin(towns)]

Echemos un vistazo a los valores que toma el campo embark_town:
titanic.embark_town.unique()
array(['Southampton', 'Cherbourg', 'Queenstown', nan], dtype=object)
Seleccionar aquellas filas en las que campo toma un cierto valor es sencillo. Por ejemplo, para seleccionar aquellas en las que el puerto de embarque es <em>Cherbourg</em> basta hacer lo siguiente:
selection = titanic[titanic.embark_town == "Cherbourg"]
selection.head()
Si quisiéramos seleccionar las filas en las que el campo en cuestión, <em>embark_town</em>, toma el valor Cherbourg o el valor Queenstown, ya no es tan obvio. La primera opción a la que podemos recurrir es incluir ambas condiciones uniéndolas el operador "o lógico":
selection = titanic[(titanic.embark_town == "Cherbourg") | (titanic.embark_town == "Queenstown")]
selection.head()
El resultado es el esperado siempre que usamos el operador | (el operador <em>or</em> devuelve un error).
En todo caso, si la lista de condiciones es larga, la mejor opción es usar el operador de pertenencia <strong>isin</strong> (en el siguiente ejemplo solo se aplica a dos opciones, pero podría ser cualquier número de ellas):
towns = ['Cherbourg', 'Queenstown']
selection = titanic[titanic.embark_town.isin(towns)]
selection.head()

El método de un DataFrame .style.set_table_styles() nos permite aplicar estilos CSS a la visualización del DataFrame. Tal y como indica la documentación, el argumento a pasar al método deberá ser una lista de diccionarios formados por valores "selector" y "props", siendo los primeros selectores CSS y los segundos parejas de tuplas formadas por atributos CSS y valores.
Es posible modificar el formato de los valores mostrados en un DataFrame pandas usando las herramientas de estilo de esta librería.
Supongamos que tenemos un cierto DataFrame:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.uniform(-5, 6, (5, 5)), columns = list("ABCDE"))
df
El objetivo en este escenario es, partiendo de un dataframe, generar bins (bloques) definidos por los valores que tome una de las características y, a continuación, dividir el dataframe según estos bins.
Veamos un ejemplo muy sencillo: Supongamos que estamos trabajando con el dataset Iris y queremos dividirlo en N grupos en función de los valores que tome la característica "sepal_length". Tendríamos que crear N bins basados en los valores de sepal_length y, a continuación, asignar cada registro del dataframe a uno de los bins.
En este escenario vamos a aplicar el método de codificación One Hot Encoding a las características categóricas del dataset Titanic proveído por seaborn. Para ello utilizaremos la función get_dummies de pandas. Comencemos cargando el dataset y examinándolo:
titanic = sns.load_dataset("titanic")
titanic.head()
Supongamos que estamos trabajando con un dataframe como el del Titanic que podemos descargar de seaborn:
import numpy as np
import seaborn as sns
titanic = sns.load_dataset("titanic")
titanic.head()
Carguemos, antes de nada, el dataset Titanic proveído por la librería seaborn:
titanic = sns.load_dataset("titanic")
titanic.head()
Echemos un vistazo a los valores que toma el campo embark_town:
titanic.embark_town.unique()
En este escenario partimos de un DataFrame conteniendo valores nulos en alguna de sus características, por ejemplo, el dataset del Titanic proveído por seaborn:
import pandas as pd
import seaborn as sns
titanic = sns.load_dataset("titanic")
titanic.head()
La función value_counts() de Pandas nos permite calcular el número de apariciones de cada elemento único en una serie Pandas, devolviendo un listado de elementos únicos y el número de apariciones de cada uno. Pero podríamos estar interesados no en el número de veces que aparece cada elemento, sino en el número de elementos que aparecen N veces, para todos los valores posibles de N.
Si queremos calcular el número de veces que cada elemento aparece en una serie pandas (o en una columna de un dataframe pandas), podemos recurrir a la función value_counts() de dicha librería. Por ejemplo, consideremos el siguiente dataframe:
df = pd.DataFrame({
"a": [1, 2, 1, 5]
})
Podemos calcular el número de apariciones de cada elemento con la siguiente instrucción:
df["a"].value_counts()
En ocasiones resulta necesario poder visualizar todas las columnas de un dataframe, aun cuando esto nos obligue a utilizar una barra de desplazamiento horizontal.
