请用Python画一只猫。

好的，以下是使用 Python 制作一只猫的代码：

import turtle

# 绘制猫头
def draw_head():
    turtle.penup()
    turtle.goto(0, 100)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(50)
    turtle.end_fill()

# 绘制猫身
def draw_body():
    turtle.penup()
    turtle.goto(0, 50)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(70)
    turtle.end_fill()

# 绘制猫耳朵
def draw_ears():
    turtle.penup()
    turtle.goto(-25, 150)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(20)
    turtle.end_fill()
    turtle.penup()
    turtle.goto(25, 150)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(20)
    turtle.end_fill()

# 绘制猫眼
def draw_eyes():
    turtle.penup()
    turtle.goto(-15, 120)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(10)
    turtle.end_fill()
    turtle.penup()
    turtle.goto(15, 120)
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(10)
    turtle.end_fill()

# 绘制猫嘴
def draw_mouth():
    turtle.penup()
    turtle.goto(0, 100)
    turtle.pendown()
    turtle.goto(0, 80)

# 绘制猫腿
def draw_legs():
    turtle.penup()
    turtle.goto(-35, 0)
    turtle.pendown()
    turtle.goto(-50, -50)
    turtle.goto(-35, -100)
    turtle.penup()
    turtle.goto(35, 0)
    turtle.pendown()
    turtle.goto(50, -50)
    turtle.goto(35, -100)

# 绘制猫尾巴
def draw_tail():
    turtle.penup()
    turtle.goto(50, -50)
    turtle.pendown()
    turtle.right(30)
    turtle.circle(70, 60)

if __name__ == '__main__':
    turtle.speed(1)
    draw_head()
    draw_body()
    draw_ears()
    draw_eyes()
    draw_mouth()
    draw_legs()
    draw_tail()
    turtle.done()

这里使用 `turtle` 模块来进行绘图，运行代码后会弹出一个窗口显示绘制出来的猫。
