python：忽略前导">>>"和“......”在互动模式？

问题描述

许多在线python示例显示了在每行之前具有正常前导>>>和...字符的交互式python会话。

Many online python examples show interactive python sessions with normal leading ">>>" and "..." characters before each line.

通常，没有办法复制此代码而不获取这些前缀。

Often, there's no way to copy this code without also getting these prefixes.

在这些情况下，如果我想在复制后将此代码重新粘贴到我自己的python解释器中，我必须这样做一些工作首先剥离这些前缀。

In these cases, if I want to re-paste this code into my own python interpreter after copying, I have to do some work to first strip off those prefixes.

有没有人知道如何让python或iPython（或任何其他python解释器）自动忽略前导>>> 和......粘贴在行上的字符？

Does anyone know of a way to get python or iPython (or any other python interpreter) to automatically ignore leading ">>>" and "..." characters on lines that are pasted in?

示例：

>>> if True:
...     print("x")
...

推荐答案

您只需关闭 autoindent 即可包含>>> 和 ... ：

You just need to either switch off autoindent to include >>> and ... in a multiline paste:

In [14]: %autoindent
Automatic indentation is: OFF
In [15]: >>> for i in range(10):
   ....: ...     pass
   ....:

In [16]: >>> for i in range(10):
   ...: ...     pass
   ...: ...
In [17]: >>> for i in range(10):
   ...: ...     pass
   ...: ...

In [18]: %autoindent
Automatic indentation is: ON

In [19]: >>> for i in range(10):
   ....:     ...     pass
   ....:
  File "<ipython-input-17-5a70fbf9a5a4>", line 2
    ...     pass
    ^
SyntaxError: invalid syntax

或者不要复制>>> ，它会正常工作：

Or don't copy the >>> and it will work fine:

In [20]: %autoindent
Automatic indentation is: OFF

In [20]:  for i in range(10):
   ....: ...     pass
   ....:
