Problem statement: Create pie-charts in python (using matplotlib.pyplot).

Program:

import matplotlib.pyplot as plt

days = [1, 2, 3, 4, 5]
slices = [7,2,2,13]
cols = ['r','y','g','b']

my_labels = ["Sleeping ", "Eating", "Working", "Playing"]

plt.pie(slices, 
        labels=my_labels, 
        colors = cols, 
startangle=45, 
        explode =(0,0.2,0,0), 
        shadow = True,
autopct = '%1.1f%%')
plt.axis('equal')
plt.legend(loc=3)
plt.show()

Output

Explanation:

The pie function plots the pie chart. Mylabels attribute is given to the label of the pie function. Explode attribute is used to explode the part of the pie. There is also a shadow attribute in the pie function for giving a shadow effect. In legend function a loc variable is passed to specify the location of the legend.
