Adding explode affect to a pandas pie chart

问题

Following this question I want to add the exploded effect to the pie chart. Consider the below code:

import pandas as pd

df = pd.DataFrame(["man", "woman", "man", "other",
                     "other", "man", "woman"], columns=["gender"])
df['gender'].value_counts(normalize=True).plot(
    kind='pie', shadow=True, autopct='%1.1f%%')

which result in

Now I want to add the explode=explode feature to the plot but I can't (e.g., here). The commands

df['gender'].value_counts(normalize=True).plot(
    kind='pie', shadow=True, autopct='%1.1f%%', explode=explode)

and

ax = df['gender'].value_counts(normalize=True).plot(
    kind='pie', shadow=True, autopct='%1.1f%%')

ax.pie(explode=explode)

results in

NameError: name 'explode' is not defined
