python中的matplotlib画饼图（数据分析与可视化）

直接开始

1、先安装pandas和matplotlib

pip install pandas
pip install matplotlib

2、然后在py文件中导入

import pandas as pd
import matplotlib.pyplot as plt

3、然后直接写代码

import pandas as pd
import matplotlib.pyplot as pltpd.set_option("max_columns",None)
plt.rcParams['font.sans-serif']=['SimHei']
plt.rcParams['axes.unicode_minus']=False# 各类别的标签
labels = ['中专', '大专', '本科', '硕士','其他']
data = [25.15,37.24,33.36,3.68,0.57]
# 饼状图中各部分的颜色
colors = ['yellowgreen', 'gold', 'lightskyblue', 'lightcoral','blue']
#对比各个部分的凸显程度
explode = (0.1,0.1,0.1,0.1,0.1)
# 绘制饼状图
plt.pie(data, labels=labels, colors=colors, textprops = {'fontsize':12, 'color':'k'},explode=explode, shadow=True,startangle=30, autopct="%0.2f%%",pctdistance=0.5)plt.show()

结束，不用谢！
