 1 import matplotlib.pyplot as plt
 2 labels = [‘Nokia‘,‘Samsung‘,‘Apple‘,‘Lumia‘]
 3 values = [10,30,45,15]
 4 colors = [‘yellow‘,‘green‘,‘red‘,‘blue‘]
 5 
 6 #其中，labels、values、colors，explode(当然explode数组中的个数与上面对应，而且每个值的范围介于0-1之前)的对应关系:‘Nokia‘-10-yellow-0,‘Samsung‘-30-green-0.1,‘Apple‘-45-red-0.2,‘Lumia‘-15-blue-0
 7 explode = [0,0.1,0.2,0]
 8 plt.pie(values,labels=labels,colors=colors,explode=explode)
 9 plt.axis(‘equal‘)
10 plt.show()
