import matplotlib.pyplot as plt
labels='Frogs','Hogs','Dogs','Logs'#定义标签
sizes=[15,30,45,10]#定义每一块的比例
colors=['yellowgreen','gold','lightskyblue','lightcoral']#定义每一块的颜色
explode=(0.2,0.1,0.1,0.1)#定义每一块偏离中心的距离
plt.pie(sizes,explode=explode,labels=labels,colors=colors,autopct='%1.1f%%',
        shadow=True,startangle=90)
plt.axis('equal')#显示为圆，避免比例压缩为椭圆
plt.show()
