使用Python的turtle库

导入库

```python

import turtle

```

创建画布

```python

screen = turtle.Screen()

screen.bgcolor("black")

```

创建画笔

```python

pen = turtle.Turtle()

pen.color("white")

pen.shape("turtle")

pen.width(3)

```

绘制月亮轮廓

```python

pen.penup()

pen.goto(-100, 0)

pen.pendown()

pen.circle(50)

```

填充月亮内部

```python

pen.begin_fill()

pen.circle(50)

pen.end_fill()

```

隐藏画笔

```python

pen.hideturtle()

```

结束绘制

```python

turtle.done()

```

使用Python的matplotlib库

导入库

```python

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

import numpy as np

```

创建画布

```python

fig = plt.figure(figsize=(10, 5))

ax = fig.add_subplot(121, projection='3d')

```

生成数据并绘制月亮

```python

x = np.linspace(0, 2 * np.pi, 100)

y = np.linspace(0, np.pi, 100)

x1 = 10 * np.outer(np.cos(x), np.sin(y))

y1 = 10 * np.outer(np.sin(x), np.sin(y))

z = 10 * np.outer(np.ones(np.size(x1)), np.cos(y1))

ax.plot_surface(x1, y1, z, color='yellow')

```

添加第二个月亮

```python

ax = fig.add_subplot(122, projection='3d')

x = np.linspace(0, 2 * np.pi, 100)

y = np.linspace(0, np.pi, 100)

x1 = 10 * np.outer(np.cos(x), np.sin(y))

y1 = 10 * np.outer(np.sin(x), np.sin(y))

z = 10 * np.outer(np.ones(np.size(x1)), np.cos(y1))

ax.plot_surface(x1, y1, z, color='yellow')

```

显示图形

```python

plt.show()

```

使用Python的turtle库绘制简单月亮

导入库

```python

import turtle

```

设置画布大小

```python

canvas = turtle.Screen()

canvas.setup(800, 800)

```

创建海龟对象

```python

t = turtle.Turtle()

```

设置画笔颜色和大小

```python

t.pensize(3)

t.pencolor("black")

```

绘制月亮

```python

t.fillcolor("yellow")

t.begin_fill()

t.circle(100)

t.end_fill()

```

隐藏海龟

```python

t.hideturtle()

```

关闭画布

```python

canvas.exitonclick()

```

这些教程图解展示了如何使用Python的turtle库和matplotlib库来绘制月亮。你可以根据需要调整参数,如内外圆的半径、颜色等,以创建不同样式的月亮图形。
