The following source code is used:
>>> from matplotlib import pyplot as plt
>>> sizes = 30,20,50
>>> lables = u'男生比例',u'女生比例',u'其他'
>>> plt.pie(sizes, labels=lables,autopct='%.3f%%', shadow=False, startangle=90)
>>> plt.axis('equal')
>>> plt.show()Just pass in the labels using the labels parameter. Python2.7 is used to write it here. Since it is in Chinese, there will be a problem that it cannot be displayed.
