How to have actual values in Matplotlib Pie Chart displayed?

To have actual or any custom values in Matplotlib pie chart displayed, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Make lists of labels, fractions, explode position and get the sum of fractions to calculate the percentage
Make a pie chart using labels, fracs and explode with autopct=lambda p: <calculation for percentage>.
To display the figure, use show() method.

Example

import matplotlib.pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

labels = ('Read', 'Eat', 'Sleep', 'Repeat')

fracs = [5, 3, 4, 1]
total = sum(fracs)
explode = (0, 0.05, 0, 0)

plt.pie(fracs, explode=explode, labels=labels,
   autopct=lambda p: '{:.0f}%'.format(p * total / 100),
   shadow=True, startangle=90)

plt.show()
