Python错误:模块“海龟”没有属性'Pen‘

Question

我试图在Pen编程中使用turtle模块的Python功能，但它给了我一个错误：

    [Clang 6.0 (clang-600.0.57)] on darwin
    Type "help", "copyright", "credits" or "license()" for more information.
    >>> import turtle
    >>> t = turtle.Pen()
    Traceback (most recent call last):
      File "<pyshell#1>", line 1, in <module>
        t = turtle.Pen()
    AttributeError: module 'turtle' has no attribute 'Pen'

Answer 1

笔里没有大写..。

它是：

import turtle
turtle.pen()

尝试执行dir(turtle)以查看可用函数列表，在其中您将看到pen

Answer 2

您的代码是正确的：

import turtle
t = turtle.Pen()

命令行会话：

% python3
Python 3.6.4 (v3.6.4:d48ecebad5, Dec 18 2017, 21:07:28) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import turtle
>>> t = turtle.Pen()
>>> exit()
% 

确保您没有自己的名为turtle.py的文件，因为这会干扰加载Python自己的turtle.py库：

% touch turtle.py
% python3
Python 3.6.4 (v3.6.4:d48ecebad5, Dec 18 2017, 21:07:28) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import turtle
>>> t = turtle.Pen()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'turtle' has no attribute 'Pen'
>>> 

这会产生与您收到的"AttributeError: module 'turtle' has no attribute 'Pen'“相同的结果。

实际解决方案:您安装了不正确的包。你应该安装PythonTurtle
