用Python画环形进度条

在Python中，你可以使用第三方库`matplotlib`和`patch`模块来创建环形进度条，也称为饼图。下面是一个简单的例子：

import matplotlib.pyplot as plt
import numpy as np

# 设置环形进度条的参数
total = 100
completed = 60
width = 0.5
outer_radius = 0.4
inner_radius = outer_radius - width

# 创建数据
angles = np.linspace(0, 2*np.pi, total+1)
bar_values = np.zeros(total+1)
bar_values[range(completed)] = completed

# 创建环形进度条
fig, ax = plt.subplots()
ax.add_patch(plt.Patch(
    annulus=annular sector=AnnularSector(
        angles start=angles[:-1], end=angles[1:], inner_radius=inner_radius,
        outer_radius=outer_radius, angle=360, facecolor='skyblue',
        edgecolor='white', linewidth=1.2),
    color='white'))

# 添加标签和标题
ax.set_title('环形进度条')
ax.set_aspect('equal')  # 保持正方形比例
plt.show()
