How do I plot a pie chart using Pandas with this data

Question

I have a data like this

ID   Sex   Smoke
1  female    1 
2    male    0
3   female   1

How do I plot a pie chart to show how many male or female smokes?

Answer 1

You can plot directly with pandas selecting pie chart:

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame({'Sex': ['female', 'male', 'female'], 'Smoke': [1, 3, 1]})

df.Smoke.groupby(df.Sex).sum().plot(kind='pie')
plt.axis('equal')
plt.show()
