如何將多行輸入粘貼到Jupyter控制檯？

Question

用於粘貼多行輸入的％paste magic可與IPython 2一起使用，但與Jupyter控制檯（在Mac OSX El Capitan上）失敗。

~ > jupyter console 
Jupyter Console 4.1.0 


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

In [2]: 

查看列出所有魔術命令的％lsmagic的輸出確實不會顯示％粘貼。

我試圖直接粘貼，但縮進會搞砸，所以顯然需要類似％paste的東西。檢查official documentation（僅在5天前更新），「粘貼」一詞甚至沒有提及。

那麼，如何將多行輸入粘貼到控制檯？

好的。找到解決方案。 Jupyter控制檯具有％cpaste魔術，其行爲與以前的％paste有所不同，但完成了工作。

%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).

    Pasting code; enter '--' alone on the line to stop. 
    :>>> a = ["world!", "Hello"] 
    :>>> print " ".join(sorted(a)) 
    :-- 
    Hello world!
