怎么使用Python绘制小熊

要使用Python绘制小熊，你可以使用Python的图形库，如turtle或matplotlib。下面是一个使用turtle库绘制小熊的示例代码：
```python
import turtle
# 设置画布和画笔
screen = turtle.Screen()
screen.bgcolor('white')
pen = turtle.Turtle()
pen.width(3)
# 绘制小熊的头部
pen.penup()
pen.goto(0, -100)
pen.pendown()
pen.circle(100)
# 绘制小熊的眼睛
pen.penup()
pen.goto(-40, 40)
pen.pendown()
pen.circle(10)
pen.penup()
pen.goto(40, 40)
pen.pendown()
pen.circle(10)
# 绘制小熊的鼻子
pen.penup()
pen.goto(0, 10)
pen.pendown()
pen.setheading(45)
pen.circle(20, 90)
# 绘制小熊的嘴巴
pen.penup()
pen.goto(-40, -20)
pen.pendown()
pen.setheading(-60)
pen.circle(40, 120)
# 绘制小熊的身体
pen.penup()
pen.goto(-100, -200)
pen.pendown()
pen.setheading(0)
pen.forward(200)
pen.setheading(60)
pen.circle(100, 120)
pen.setheading(180)
pen.forward(200)
pen.setheading(-60)
pen.circle(100, 120)
# 绘制小熊的胳膊
pen.penup()
pen.goto(-100, -200)
pen.pendown()
pen.setheading(-135)
pen.forward(100)
pen.setheading(-45)
pen.forward(100)
pen.penup()
pen.goto(100, -200)
pen.pendown()
pen.setheading(-45)
pen.forward(100)
pen.setheading(45)
pen.forward(100)
# 绘制小熊的腿
pen.penup()
pen.goto(-100, -350)
pen.pendown()
pen.setheading(-45)
pen.forward(100)
pen.setheading(-135)
pen.forward(100)
pen.penup()
pen.goto(100, -350)
pen.pendown()
pen.setheading(-135)
pen.forward(100)
pen.setheading(-45)
pen.forward(100)
turtle.done()
```
运行上述代码，就可以在turtle图形窗口中看到绘制的小熊了。你可以根据需要调整代码中的参数来调整小熊的大小和位置。
