python绘制自定义蟒蛇

在Python中，我们可以使用matplotlib库来绘制自定义图形，包括一些创意的形状，比如蟒蛇。你可以通过组合线、弧线和其他几何元素来创建这种效果。下面是一个简单的示例，展示如何使用`Path`对象和`patch`模块来绘制一条基本的蟒蛇：

import matplotlib.pyplot as plt
from matplotlib.path import Path
import numpy as np

# 定义蟒蛇的路径数据
vertices = [(0, 0), (50, 20), (75, 0), (65, -30), (30, -40), (10, 0)]
codes = [Path.MOVETO,
         Path.LINETO,
         Path.CURVE3,
         Path.CURVE3,
         Path.CURVE3,
         Path.CLOSEPOLY]

# 创建Path对象
snake_path = Path(vertices, codes)

# 设置填充颜色和边界颜色
fill_color = 'gray'
edge_color = 'black'

# 创建一个圆形作为蛇头
head_radius = 10
head_vertices = [(0, 0), (head_radius, 0), (head_radius, head_radius)]
head_codes = [Path.MOVETO, Path.CURVE4, Path.CURVE4]
head_path = Path(head_vertices, head_codes)

# 绘制蟒蛇
fig, ax = plt.subplots()
ax.set_xlim(-50, 80)
ax.set_ylim(-50, 50)

path_patch = patches.PathPatch(snake_path, facecolor=fill_color, edgecolor=edge_color)
ax.add_patch(path_patch)
head_patch = patches.PathPatch(head_path, facecolor='white', edgecolor=edge_color)
ax.add_patch(head_patch)

plt.show()
