Python是一種流行的編程語言，可以用它來制作許多有趣的應用，包括圖形繪制。Python里一個非常有趣的圖形繪制包是turtle，它可以讓我們繪制出各種漂亮的圖案。

# 導入turtle庫
import turtle
# 設置畫布大小和初始位置
turtle.setup(600, 600)
turtle.penup()
turtle.goto(-150, 150)
turtle.pendown()
# 繪制皮卡丘
def draw_pikachu():
turtle.circle(60, 90)
turtle.fd(60)
turtle.circle(60, 90)
turtle.fd(60)
turtle.circle(45, 180)
turtle.fd(30)
turtle.circle(20, 180)
turtle.fd(10)
turtle.circle(45, 180)
turtle.fd(30)
turtle.circle(20, 180)
turtle.penup()
turtle.goto(-75, 75)
turtle.pendown()
turtle.begin_fill()
turtle.circle(15)
turtle.end_fill()
turtle.penup()
turtle.goto(75, 75)
turtle.pendown()
turtle.begin_fill()
turtle.circle(15)
turtle.end_fill()
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()
turtle.color('#feba32')
turtle.begin_fill()
turtle.circle(100)
turtle.end_fill()
# 繪制皮卡丘的眼睛和嘴巴
def draw_face():
turtle.penup()
turtle.goto(-40, 110)
turtle.pendown()
turtle.color('black')
turtle.begin_fill()
turtle.circle(4)
turtle.end_fill()
turtle.penup()
turtle.goto(40, 110)
turtle.pendown()
turtle.begin_fill()
turtle.circle(4)
turtle.end_fill()
turtle.penup()
turtle.goto(0, 60)
turtle.pendown()
turtle.width(6)
turtle.color('black')
turtle.right(60)
turtle.fd(50)
turtle.penup()
turtle.goto(-30, 30)
turtle.pendown()
turtle.right(48)
turtle.fd(38)
turtle.penup()
turtle.goto(30, 30)
turtle.pendown()
turtle.right(84)
turtle.fd(38)
# 調用函數，繪制皮卡丘和表情
draw_pikachu()
draw_face()
# 隱藏畫筆
turtle.hideturtle()
# 等待關閉
turtle.done()

以上就是用Python turtle包繪制皮卡丘的全部代碼。我們可以通過調用turtle的各種函數，像玩樂高積木一樣構建出我們想要的圖案，非常有趣！
