用python画一个皮卡丘

要用Python画一个皮卡丘，需要用到Python的turtle库。以下是一个简单的代码示例：

import turtle

turtle.speed(10)

# 画皮卡丘的头
turtle.color('yellow')
turtle.begin_fill()
turtle.circle(100)
turtle.end_fill()

# 画皮卡丘的眼睛
turtle.penup()
turtle.goto(-40, 120)
turtle.pendown()
turtle.color('black')
turtle.begin_fill()
turtle.circle(20)
turtle.end_fill()

turtle.penup()
turtle.goto(40, 120)
turtle.pendown()
turtle.color('black')
turtle.begin_fill()
turtle.circle(20)
turtle.end_fill()

# 画皮卡丘的眼珠
turtle.penup()
turtle.goto(-40, 130)
turtle.pendown()
turtle.color('white')
turtle.begin_fill()
turtle.circle(8)
turtle.end_fill()

turtle.penup()
turtle.goto(40, 130)
turtle.pendown()
turtle.color('white')
turtle.begin_fill()
turtle.circle(8)
turtle.end_fill()

# 画皮卡丘的鼻子
turtle.penup()
turtle.goto(0, 70)
turtle.pendown()
turtle.color('black')
turtle.begin_fill()
turtle.circle(15)
turtle.end_fill()

# 画皮卡丘的嘴巴
turtle.penup()
turtle.goto(-60, 10)
turtle.pendown()
turtle.color('black')
turtle.right(45)
turtle.circle(80, 90)

# 画皮卡丘的脸颊
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()
turtle.color('red')
turtle.begin_fill()
turtle.circle(50)
turtle.end_fill()

# 画皮卡丘的耳朵
turtle.penup()
turtle.goto(-90, 160)
turtle.pendown()
turtle.color('yellow')
turtle.begin_fill()
turtle.right(45)
turtle.circle(60, 90)
turtle.goto(-90, 160)
turtle.end_fill()

turtle.penup()
turtle.goto(90, 160)
turtle.pendown()
turtle.color('yellow')
turtle.begin_fill()
turtle.right(180)
turtle.circle(-60, 90)
turtle.goto(90, 160)
turtle.end_fill()

# 完成
turtle.done()

运行上述代码，即可在turtle绘图窗口中看到一个皮卡丘的图像。可以根据需要调整一些参数，如颜色、大小、位置等，以得到更符合自己想象的效果。
