用于粘贴多行输入的%paste magic可与IPython 2配合使用,但在Jupyter控制台上失败(在Mac OSX El Capitan上)。

~ > jupyter console
Jupyter Console 4.1.0


In [1]: %paste
ERROR: Line magic function `%paste` not found.

In [2]:

查看列出所有魔术命令的%lsmagic输出确实没有显示%paste。

我试图直接粘贴,但缩进变得搞砸了,所以显然需要%paste这样的东西。检查official documentation(仅在5天前更新),甚至没有提到“粘贴”这个词。

那么,如何将多行输入粘贴到控制台?

确定。找到了解决方案。 Jupyter控制台具有%cpaste魔法,其行为与之前的%粘贴略有不同,但可以完成工作。

%cpaste:
Paste & execute a pre-formatted code block from clipboard.

You must terminate the block with '--' (two minus-signs) or Ctrl-D
alone on the line. You can also provide your own sentinel with '%paste
-s %%' ('%%' is the new sentinel for this operation).

The block is dedented prior to execution to enable execution of method
definitions. '>' and '+' characters at the beginning of a line are
ignored, to allow pasting directly from e-mails, diff files and
doctests (the '...' continuation prompt is also stripped).  The
executed block is also assigned to variable named 'pasted_block' for
later editing with '%edit pasted_block'.

You can also pass a variable name as an argument, e.g. '%cpaste foo'.
This assigns the pasted block to variable 'foo' as string, without
dedenting or executing it (preceding >>> and + is still stripped)

'%cpaste -r' re-executes the block previously entered by cpaste.
'%cpaste -q' suppresses any additional output messages.

Do not be alarmed by garbled output on Windows (it's a readline bug).
Just press enter and type -- (and press enter again) and the block
will be what was just pasted.

IPython statements (magics, shell escapes) are not supported (yet).
