    没有任何编程知识的小白 最近在自学 Python 学习 turtle 中

    一开始是 Python 3.8.1

    form turtle import *
    color("red", "greed"}
    shape("turtle")
    done()

    @jdhao 新手不懂 V2EX 编辑器 误点击发布了 问题没有编辑好就发布出来了
    没有任何编程知识的小白 最近在自学 Python 学习 turtle 中

    一开始是 Python 3.8.1 x64 win10 x64
    代码
    ```Python
    form turtle import *
    color("red", "green")
    shape("turtle")
    done()
    ```
    参考文档
    https://docs.python.org/zh-cn/3.8/library/turtle.html

    运行报错

    难道环境配置错了?
    后来注册了 cloud studio 预置环境是 Python 2.7 x64 Ubuntu
    代码
    ```Python
    import turtle
    turtle.color("red", "green")
    turtle.shape("turtle")
    ```
    参考文档
    https://docs.python.org/zh-cn/2.7/library/turtle.html

    还是运行错误 我要裂开了

    @victory py2 是因为没装 python-tk 这个库吧。py3 直接 import turtle 不行吗?你 turtle 库安装了吗?我看 py3 里 pip install 安装 turtle 的时候得下载包吧 setup.py 改一下才能装。

    @zanelee 额 turtle 是内置模块 or 自带的标准库 不需要安装吧
    Python3 为什么那么写 因为 官方参考文档就是那么写的 docs.python.org/zh-cn/3.8/library/turtle.html
