帮我用python编写一个画出皮卡丘的程序

好的，以下是一份用 Python 语言编写的画皮卡丘程序，希望对您有所帮助：

import turtle

# 画出一个黑色圆形
def circle(color):
    turtle.fillcolor(color)
    turtle.begin_fill()
    turtle.circle(60)
    turtle.end_fill()

# 画出一个黑色椭圆形
def ellipse():
    turtle.fillcolor('black')
    turtle.begin_fill()
    for i in range(2):
        turtle.circle(80, 45)
        turtle.circle(40, 45)
    turtle.end_fill()

# 画出一个电气表盘状的东西
def semicircle(x, y, r, color):
    turtle.penup()
    turtle.goto(x, y-r)
    turtle.pendown()
    turtle.fillcolor(color)
    turtle.begin_fill()
    turtle.circle(r, 180)
    turtle.end_fill()

# 画出一个红色五角星
def star():
    turtle.penup()
    turtle.goto(-25, 80)
    turtle.pendown()
    turtle.fillcolor('red')
    turtle.begin_fill()
    for i in range(5):
        turtle.forward(50)
        turtle.right(144)
    turtle.end_fill()

# 头
def head():
    circle('yellow')

    # 左耳
    turtle.penup()
    turtle.goto(-130, 105)
    turtle.pendown()
    circle('black')

    # 右耳
    turtle.penup()
    turtle.goto(70, 105)
    turtle.pendown()
    circle('black')

    # 面部特征
    semicircle(-45, 0, 30, 'white')   # 左眼白色部分
    semicircle(45, 0, 30, 'white')   # 右眼白色部分
    semicircle(-37, 0, 12, 'black')   # 左眼黑色部分
    semicircle(37, 0, 12, 'black')   # 右眼黑色部分
    semicircle(-37, 10, 5, 'white')   # 左眼珠
    semicircle(37, 10, 5, 'white')   # 右眼珠
    semicircle(0, -25, 45, 'red')   # 嘴

    # 腮
    turtle.penup()
    turtle.goto(-95, -35)
    turtle.pendown()
    circle('red')
    turtle.penup()
    turtle.goto(95, -35)
    turtle.pendown()
    circle('red')

# 身体
def body():
    circle('yellow')

    # 腹部
    turtle.penup()
    turtle.goto(0, -110)
    turtle.pendown()
    ellipse()

    # 尾巴
    turtle.penup()
    turtle.goto(120, -50)
    turtle.pendown()
    semicircle(0, 0, 30, 'yellow')
    turtle.penup()
    turtle.goto(105, -50)
    turtle.pendown()
    semicircle(0, 0, 15, 'black')
    turtle.penup()
    turtle.goto(90, -50)
    turtle.pendown()
    semicircle(0, 0, 15, 'yellow')
    turtle.penup()
    turtle.goto(75, -50)
    turtle.pendown()
    semicircle(0, 0, 15, 'black')

# 整体
def pikachu():
    head()
    body()
    star()

turtle.speed(0)
pikachu()
turtle.done()

希望这个程序能够帮到您！
