一、下载

turtle是python中模块中自带的一般不需要下载

如果报错如下，需要下载自己下载python-tk模块,详细请看python-tk下载
(mac的话可以直接用brew install python-tk)

(myenv) yinhao@yinhaos-MacBook-Pro python % /Users/yinhao/Desktop/Program/python/myenv/bin/python /Users/yinhao/Desktop/Program/python/绘制.py
Traceback (most recent call last):
  File "/Users/yinhao/Desktop/Program/python/绘制.py", line 1, in <module>
    import turtle
  File "/opt/homebrew/Cellar/python@3.12/3.12.2_1/Frameworks/Python.framework/Versions/3.12/lib/python3.12/turtle.py", line 101, in <module>
    import tkinter as TK
  File "/opt/homebrew/Cellar/python@3.12/3.12.2_1/Frameworks/Python.framework/Versions/3.12/lib/python3.12/tkinter/__init__.py", line 38, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
    ^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named '_tkinter'

二、基础知识

更多请看: turtle官方

import turtle
# 圆
turtle.circle(100)
# 目前方向前进,forword可以用fd代替
turtle.forword(100) 
# 返回back = bk,后退100
turtle.back(100)
# 转向,左右各转九十度
turtle.right(90)
turtle.left(90)

# 足迹的宽度 width = pensize
turtle.width(10)

# 足迹颜色
turtle.color('string')

# 运动速度 10 最大
turtle.speed(3)

# 不留显示足迹
turtle.penup()

# 让窗口演示完后自动关闭
turtle.bye()
# 让窗口最后不自动关闭
turtle.done()

三、实现效果

1、圆

import turtle
turtle.circle(100)

2、五

import turtle

turtle.speed(3)
turtle.left(-180)
turtle.forward(100)
turtle.left(90)
turtle.forward(100)
turtle.left(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(100)

turtle.done()

3、蛇

import turtle as t
t.penup()
t.bk(350)
t.pendown()
t.color('purple')
t.right(50)
t.width(15)
for i in range(4):
    t.circle(40,50)
    t.circle(40,50)
    t.circle(-40,50)
    t.circle(-40,50)

t.color('green')
t.width(20)
t.forward(30)
t.done()

5、循环的正方形

import turtle as t

for i in range(100):
    t.left(90)
    t.fd(5*i)
t.done()
