Python 代码绘制爱心

如何用 Python 代码绘制爱心?

使用 Python 代码绘制爱心需要以下步骤:

1. 导入 matplotlib 库

<code class="python">import matplotlib.pyplot as plt</code>
Copy after login

2. 定义 X 和 Y 坐标

使用 Paramteric Equation (参数方程) 来生成爱心形状的 X 和 Y 坐标:

<code class="python">theta = np.linspace(0, 2 * np.pi, 200)
x = np.cos(theta) ** 3
y = np.sin(theta) ** 3</code>
Copy after login

3. 绘制曲线

使用 plt.plot 函数来绘制爱心曲线:

<code class="python">plt.plot(x, y)</code>
Copy after login

4. 设置图形选项

设置线条宽度、颜色和标题:

<code class="python">plt.linewidth = 3
plt.color = 'red'
plt.title('Heart')</code>
Copy after login

5. 显示图形

使用 plt.show 函数来显示绘制的爱心图形:

<code class="python">plt.show()</code>
Copy after login

完整代码:

<code class="python">import numpy as np
import matplotlib.pyplot as plt

theta = np.linspace(0, 2 * np.pi, 200)
x = np.cos(theta) ** 3
y = np.sin(theta) ** 3

plt.plot(x, y)
plt.linewidth = 3
plt.color = 'red'
plt.title('Heart')
plt.show()</code>
Copy after login
