如何用代码绘制一个操场

在Python中，我们可以使用matplotlib库来绘制一个简单的操场模型。这里是一个基本的例子，我们假设操场是一个长方形，中心有一个半径为R的圆形篮球场：

import matplotlib.pyplot as plt
import numpy as np

# 操场和篮球场尺寸
playground_length = 80  # 操场长度 (米)
playground_width = 50   # 操场宽度 (米)
basketball_court_radius = 10  # 篮球场半径 (米)

def draw_playground():
    fig, ax = plt.subplots()

    # 绘制操场边界
    ax.plot([-playground_length / 2, playground_length / 2], [0, 0], color='gray', linestyle='dashed')
    ax.plot([0, 0], [-playground_width / 2, playground_width / 2], color='gray', linestyle='dashed')

    # 绘制篮球场圆心
    court_center = (-playground_length / 4, playground_width / 4)
    ax.scatter(court_center[0], court_center[1], color='red', marker='o', s=200)

    # 绘制篮球场圆
    circle = plt.Circle(court_center, basketball_court_radius, fill=False, edgecolor='black')
    ax.add_patch(circle)

    # 设置坐标轴范围和标题
    ax.set_xlim(-playground_length / 2, playground_length / 2)
    ax.set_ylim(-playground_width / 2, playground_width / 2)
    ax.set_aspect('equal')  # 保持纵横比例一致
    ax.set_title('简单操场示意图')

draw_playground()
plt.show()
