星空创意编程可以通过以下步骤进行教程:

使用turtle模块绘制星空

导入库

```python

import turtle

import random

```

设置画布

```python

screen = turtle.Screen()

screen.setup(width=800, height=600)

screen.bgcolor("black")

screen.tracer(0)

```

创建海龟对象

```python

star = turtle.Turtle()

star.hideturtle()

star.speed(0)

star.color("white")

```

绘制星星函数

```python

def draw_star(x, y, size, spikes):

star.penup()

star.goto(x, y)

star.pendown()

angle = 180 - (180 / spikes)

for _ in range(spikes):

star.forward(size)

star.right(angle)

```

随机生成星星

```python

for _ in range(150):

x = random.randint(-390, 390)

y = random.randint(-290, 290)

size = random.randint(2, 6)

spikes = random.randint(3, 5)

draw_star(x, y, size, spikes)

```

关闭画布

```python

screen.exitonclick()

```

使用matplotlib绘制3D星空

安装必要的库

```bash

pip install numpy matplotlib

```

导入库并设置参数

```python

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

np.random.seed(42)

n_stars = 1000

x = np.random.uniform(-1, 1, n_stars)

y = np.random.uniform(-1, 1, n_stars)

z = np.random.uniform(-1, 1, n_stars)

sizes = np.random.uniform(10, 100, n_stars)

colors = np.random.uniform(0, 1, (n_stars, 3))

```

创建3D画布

```python

fig = plt.figure(figsize=(10, 8))

ax = fig.add_subplot(111, projection='3d')

```

绘制星星

```python

for i in range(n_stars):

ax.scatter(x[i], y[i], z[i], s=sizes[i], c=colors[i], marker='o')

```

显示图形

```python

plt.show()

```

总结

以上是使用Python的turtle模块和matplotlib库绘制星空的两种方法。turtle模块适合初学者和简单的星空图案绘制,而matplotlib库则适合创建更为复杂和逼真的3D星空效果。根据需求和编程经验,可以选择合适的方法进行尝试。
