Python 动态玫瑰花代码揭秘：开发中需小心的三大陷阱

```python import numpy as np import matplotlib.pyplot as plt from matplotlib.animation import FuncAnimation fig, ax = plt.subplots(figsize=(6, 6)) ax.set_xlim(-2, 2) ax.set_ylim(-2, 2) ax.set_aspect('equal') ax.axis('off') theta = np.linspace(0, 2 * np.pi, 1000) t = np.linspace(0, 2 * np.pi, 200) def rose_curve(time): k = 5 # 花瓣数量参数 r = np.sin(k * theta + time) * np.cos(theta + time) x = r * np.cos(theta) y = r * np.sin(theta) return x, y line, = ax.plot([], [], 'c-', lw=2) def init(): line.set_data([], []) return line, def update(frame): x, y = rose_curve(frame) line.set_data(x, y) line.set_color(plt.cm.viridis(frame / (2 * np.pi))) return line, ani = FuncAnimation(fig, update, frames=t, init_func=init, blit=True, interval=50) plt.show() ``` 我在以往的开发过程中，碰到过以下几点需要格外小心处理的地方： - 三角函数参数调整不当会导致图形扭曲或不对称 - 动画帧率设置过高可能造成系统资源占用过大 - 颜色映射未归一化可能导致色彩显示异常 ######[AI写代码神器 | 326点数解答 | 2025-10-29 18:35:24]
