You can use pie() function from pyplot to draw pie charts in python. First you need to install matplotlib:

pip install matplotlib

Then you can create pie charts by providing the sizes and labels:

import matplotlib.pyplot as plt

labels = 'Charging', 'Number', 'Share'
sizes = [20, 9, 15.5]

fig1, ax1 = plt.subplots()
ax1.pie(sizes, labels=labels, startangle=90)
ax1.axis('equal')

plt.show()
