Python调用turtle

你可以使用Python的turtle模块来调用海龟图形库。这个库提供了一组函数，可以让海龟在屏幕上绘制图形。下面是一个简单的例子，演示如何使用turtle模块绘制一个正方形：

import turtle

# 创建一个海龟对象
t = turtle.Turtle()

# 绘制正方形
for _ in range(4):
    t.forward(100)  # 向前移动100个像素
    t.right(90)  # 右转90度

# 关闭窗口
turtle.done()

运行这段代码，你会看到一个正方形在屏幕上被绘制出来。你还可以使用其他函数来控制海龟的移动和绘制，比如`backward()`、`left()`、`circle()`等等。希望这能帮到你！如果有更多问题，请继续提问。

Python调用turtle库画皮卡丘

好的，我可以为您展示如何使用Python的Turtle库来画皮卡丘。

下面是绘制皮卡丘的Python代码：

import turtle

# 创建一个新窗口
win = turtle.Screen()
win.bgcolor("white")

# 画布的大小
win.setup(width=600, height=600)

# 将画笔移到屏幕中央，准备画脸
face = turtle.Turtle()
face.color("black")
face.fillcolor("yellow")
face.penup()
face.goto(0, -100)
face.pendown()
face.begin_fill()
face.circle(200)
face.end_fill()

# 画左耳
left_ear = turtle.Turtle()
left_ear.color("black")
left_ear.fillcolor("black")
left_ear.penup()
left_ear.goto(-150, 180)
left_ear.pendown()
left_ear.begin_fill()
left_ear.right(135)
left_ear.circle(100, -90)
left_ear.left(90)
left_ear.circle(100, -45)
left_ear.end_fill()

# 画右耳
right_ear = turtle.Turtle()
right_ear.color("black")
right_ear.fillcolor("black")
right_ear.penup()
right_ear.goto(150, 180)
right_ear.pendown()
right_ear.begin_fill()
right_ear.left(135)
right_ear.circle(-100, -90)
right_ear.right(90)
right_ear.circle(-100, -45)
right_ear.end_fill()

# 画左眼
left_eye = turtle.Turtle()
left_eye.color("black")
left_eye.fillcolor("white")
left_eye.penup()
left_eye.goto(-80, 50)
left_eye.pendown()
left_eye.begin_fill()
left_eye.circle(40)
left_eye.end_fill()

# 画右眼
right_eye = turtle.Turtle()
right_eye.color("black")
right_eye.fillcolor("white")
right_eye.penup()
right_eye.goto(80, 50)
right_eye.pendown()
right_eye.begin_fill()
right_eye.circle(40)
right_eye.end_fill()

# 左眼珠
left_pupil = turtle.Turtle()
left_pupil.color("black")
left_pupil.fillcolor("black")
left_pupil.penup()
left_pupil.goto(-80, 20)
left_pupil.pendown()
left_pupil.begin_fill()
left_pupil.circle(20)
left_pupil.end_fill()

# 画右眼珠
right_pupil = turtle.Turtle()
right_pupil.color("black")
right_pupil.fillcolor("black")
right_pupil.penup()
right_pupil.goto(80, 20)
right_pupil.pendown()
right_pupil.begin_fill()
right_pupil.circle(20)
right_pupil.end_fill()

# 画鼻子
nose = turtle.Turtle()
nose.color("black")
nose.fillcolor("black")
nose.penup()
nose.goto(0, 60)
nose.pendown()
nose.begin_fill()
nose.circle(30)
nose.end_fill()

# 画嘴巴
mouth = turtle.Turtle()
mouth.color("black")
mouth.penup()
mouth.goto(-100, -40)
mouth.pendown()
mouth.right(90)
mouth.circle(100, 180)

# 使窗口保持打开状态
turtle.done()

运行上述代码后，您可以在Turtle窗口中看到绘制的皮卡丘。
