使用python，一组同心圆，外圆半径6，内圆半径为3，两条过圆心的夹角为60度的直线，将内圆弧，外圆弧和单方向的两个边组成的扇形的点保存为numpy

import numpy as np
import math

# 定义圆心和半径
center = np.array([0, 0])
r1 = 6
r2 = 3

# 定义两条直线的夹角
angle = 60

# 定义扇形的起始角度和结束角度
start_angle = 0
end_angle = angle

# 定义圆心角的步长
step = 0.1

# 定义扇形的点
points = []

# 外圆弧
for i in np.arange(start_angle, end_angle, step):
x = center[0] + r1 * math.cos(math.radians(i))
y = center[1] + r1 * math.sin(math.radians(i))
points.append([x, y])

# 单方向的第一条边
for i in np.arange(end_angle, 360 - angle, step):
x = center[0] + r1 * math.cos(math.radians(i))
y = center[1] + r1 * math.sin(math.radians(i))
points.append([x, y])

# 内圆弧
for i in np.arange(360 - angle, 360 - start_angle, step):
x = center[0] + r2 * math.cos(math.radians(i))
y = center[1] + r2 * math.sin(math.radians(i))
points.append([x, y])

# 单方向的第二条边
for i in np.arange(360 - start_angle, 360, step):
x = center[0] + r2 * math.cos(math.radians(i))
y = center[1] + r2 * math.sin(math.radians(i))
points.append([x, y])

# 将点转化为numpy数组
points = np.array(points)

print(points)
