可以使用Python的turtle模块来画一个简单的雪人。下面是一个示例代码：

```python

import turtle

# 画头部

turtle.fillcolor("white")

turtle.begin_fill()

turtle.circle(60)

turtle.end_fill()

# 画身体

turtle.penup()

turtle.goto(0, -80)

turtle.pendown()

turtle.fillcolor("white")

turtle.begin_fill()

turtle.circle(80)

turtle.end_fill()

# 画眼睛

turtle.penup()

turtle.goto(-20, 50)

turtle.pendown()

turtle.fillcolor("black")

turtle.begin_fill()

turtle.circle(10)

turtle.end_fill()

turtle.penup()

turtle.goto(20, 50)

turtle.pendown()

turtle.begin_fill()

turtle.circle(10)

turtle.end_fill()

# 画嘴巴

turtle.penup()

turtle.goto(-25, 20)

turtle.pendown()

turtle.pencolor("red")

turtle.pensize(3)

turtle.right(90)

turtle.circle(25, 180)

# 画身体上的按钮

turtle.penup()

turtle.goto(0, -20)

turtle.pendown()

turtle.fillcolor("black")

turtle.begin_fill()

turtle.circle(8)

turtle.end_fill()

turtle.penup()

turtle.goto(0, -50)

turtle.pendown()

turtle.fillcolor("black")

turtle.begin_fill()

turtle.circle(8)

turtle.end_fill()

turtle.penup()

turtle.goto(0, -80)

turtle.pendown()

turtle.fillcolor("black")

turtle.begin_fill()

turtle.circle(8)

turtle.end_fill()

turtle.done()

```

在Python环境中运行此代码，即可看到一个简单的雪人图案。您可以根据需要进行修改和优化。
