手把手教你用itchat统计好友信息，了解一下？

import itchat

itchat.auto_login(hotReload=True)
itchat.dump_login_status()

we_friend = itchat.get_friends(update=True)[:]

total = len(we_friend[1:])
for fri_info in we_friend[1:]:
    sex = fri_info['sex']
    # 如果sex=1 代表男性 sex=2代表女性

        man += 1
    elif sex == 2:
        woman += 1
    else:
        other += 1

man_ratio = int(man)/total * 100
woman_ratio = int(woman)/total * 100
other_ratio = int(other)/total * 100

plt.rcParams['font.sans-serif'] = ['SimHei']    # 用来正常显示中文标签
plt.rcParams['axes.unicode_minus'] = False  # 用来正常显示负号
plt.figure(figsize=(5, 5))  # 绘制的图片为正圆
sex_li = ['男', '女', '其他']
radius = [0.01, 0.01, 0.01]  # 设定各项距离圆心n个半径

plt.pie(proportion, explode=radius, labels=sex_li, colors=colors, autopct='%.2f%%')   # 绘制饼图

# 加入图例 loc =  'upper right' 位于右上角 bbox_to_anchor=[0.5, 0.5] # 外边距 上边 右边 borderaxespad = 0.3图例的内边距
plt.legend(loc="upper right", fontsize=10, bbox_to_anchor=(1.1, 1.1), borderaxespad=0.3)

# 绘制标题
plt.title('微信好友性别比例')    

# 展示
plt.show()

在terminal中：cd ~/.cache/matplotlib

把.cache下面的matplotlib文件夹删除。
