在Python中的饼图旁边打印元素总和

import matplotlib.pyplot as plt

# 饼图数据
labels = ['A', 'B', 'C', 'D']
sizes = [30, 20, 40, 10]

# 绘制饼图
fig, ax = plt.subplots()
ax.pie(sizes, labels=labels, autopct='%1.1f%%')

# 计算元素总和
total = sum(sizes)

# 在饼图旁边打印元素总和
ax.text(1.2, 0.5, f'Total: {total}', transform=ax.transAxes, fontsize=12, verticalalignment='center')

# 显示图形
plt.show()
