IPython正斜杠文档 [英] IPython forward slash documentation

问题描述

我不小心在IPython中发现了此功能:

I accidentally discovered this feature in IPython:

In [126]: def blah(): return 5

In [127]: /blah
Out[127]: 5

In [128]: /range 5 2 4
Out[128]: range(5, 2, 4)

In [133]: /int '100' base=16
Out[133]: 256

以正斜杠开头的行将带有逗号和自动插入函数调用括号.

A line starting with a forward slash will have commas and function call parens automatically inserted.

我在哪里可以找到更多?我似乎找不到它的文档.

Where do I find out more? I can't seem to find the docs for it.

推荐答案

如果在ipython中键入?，您将获得内置文档:

If you type ? in ipython you will get the builtin documentation:

 You can force auto-parentheses by using '/' as the first character
     of a line.  For example::

          In [1]: /globals             # becomes 'globals()'

     Note that the '/' MUST be the first character on the line!  This
     won't work::

          In [2]: print /globals    # syntax error

     In most cases the automatic algorithm should work, so you should
     rarely need to explicitly invoke /. One notable exception is if you
     are trying to call a function with a list of tuples as arguments (the
     parenthesis will confuse IPython)::

          In [1]: zip (1,2,3),(4,5,6)  # won't work

     but this will work::

          In [2]: /zip (1,2,3),(4,5,6)
          ------> zip ((1,2,3),(4,5,6))
          Out[2]= [(1, 4), (2, 5), (3, 6)]

     IPython tells you that it has altered your command line by
     displaying the new command line preceded by -->.  e.g.::

          In [18]: callable list
          -------> callable (list)
