Python -如何在饼图中将autopct文本更改为白色和粗体？

import matplotlib.pyplot as plt

sizes = [15, 30, 45, 10]  # 饼图各部分的大小
labels = ['A', 'B', 'C', 'D']  # 饼图各部分的标签

fig, ax = plt.subplots()
_, _, autotexts = ax.pie(sizes, labels=labels, autopct='%1.1f%%')

# 设置文本颜色为白色
for autotext in autotexts:
    autotext.set_color('white')

# 设置文本为粗体
for autotext in autotexts:
    autotext.set_fontweight('bold')

plt.show()
