import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.mplot3d import Axes3D

m = 51212.
f = 40742.
m_perc = m/(m+f)
f_perc = f/(m+f)  #男女比例

color = ['navy','lightcoral']
labels = ["Male","Female"]
fig = plt.figure(figsize = (8,8))
paches,texts,autotexts = plt.pie([m_perc,f_perc],labels = labels,
        colors = color,autopct = '%1.1f%%',
       explode = [0,0.05],)
# autopct 用百分比展示
# explode 每个板块之间的间隔

#去修改text的颜色和字体大小
for text in texts + autotexts: #图形内外字母的都需要改变大小
    text.set_fontsize(20)
for text in autotexts: #只改变图内字母的颜色
    text.set_color('white')

输出结果图:
在这里插入图片描述

// An highlighted block
var foo = 'bar';
