画星星
导入库
```python
import turtle
import random
```
定义画星星的函数
```python
def draw_star(x, y, size):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
angle = 120
for _ in range(5):
turtle.forward(size)
turtle.right(angle)
turtle.forward(size)
turtle.right(72 - angle)
```
让星星布满天空
```python
screen = turtle.Screen()
screen.bgcolor("black")
turtle.speed(1)
turtle.color("white")
for _ in range(100):
size = random.randint(20, 50)
x = random.randint(-200, 200)
y = random.randint(-200, 200)
draw_star(x, y, size)
turtle.done()
```
画月亮
定义画月亮的函数
```python
def draw_moon(x, y, size):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.color("gray")
turtle.begin_fill()
turtle.circle(size)
turtle.left(90)
turtle.circle(size / 2)
turtle.end_fill()
```
在画布上绘制月亮
```python
screen = turtle.Screen()
screen.bgcolor("black")
turtle.speed(1)
turtle.color("white")
for _ in range(100):
size = random.randint(20, 50)
x = random.randint(-200, 200)
y = random.randint(-200, 200)
draw_star(x, y, size)
draw_moon(0, 0, 100)
turtle.done()
```
综合示例
将上述代码整合在一起,可以绘制出满天繁星和月亮的效果:
```python
import turtle
import random
画星星的函数
def draw_star(x, y, size):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
angle = 120
for _ in range(5):
turtle.forward(size)
turtle.right(angle)
turtle.forward(size)
turtle.right(72 - angle)
画月亮的函数
def draw_moon(x, y, size):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.color("gray")
turtle.begin_fill()
turtle.circle(size)
turtle.left(90)
turtle.circle(size / 2)
turtle.end_fill()
让星星布满天空
screen = turtle.Screen()
screen.bgcolor("black")
turtle.speed(1)
turtle.color("white")
for _ in range(100):
size = random.randint(20, 50)
x = random.randint(-200, 200)
y = random.randint(-200, 200)
draw_star(x, y, size)
在画布上绘制月亮
draw_moon(0, 0, 100)
turtle.done()
```
运行上述代码,将会弹出一个窗口,窗口中绘制了一个黑色背景,中间有一个白色月亮和满天的白色星星。你可以根据需要调整代码中的参数,如画笔的颜色、大小、位置等,来绘制不同样式的星星和月亮。
