ipython不添加新行

如何解决ipython不添加新行

考虑ipython repl：

$ ipython
Python 3.6.8 (default,Aug  7 2019,17:28:10)
Type 'copyright','credits' or 'license' for more information
IPython 7.16.1 -- An enhanced Interactive Python. Type '?' for help.

[ins] In [1]: x = 2

[ins] In [2]: y = 2

[ins] In [3]: 

相反，请考虑普通的python repl：

$ python
Python 3.6.8 (default,17:28:10)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux
Type "help","copyright","credits" or "license" for more information.
>>> x = 2
>>> y = 2
>>> 

如您所见，ipython repl添加了很多不必要的（我认为）新行语句，而python repl更为简洁。

有没有一种方法可以禁用这些新行？ （请注意，我知道这一点：https://ipython.readthedocs.io/en/stable/config/details.html，可以在其中更改在提示符下显示的内容。但是，找不到在提示符之间禁用新行的选项）

解决方法

从ipython选项开始--nosep。

$ ipython --nosep
Python 3.8.3 | packaged by conda-forge | (default,Jun  1 2020,17:43:00) 
Type 'copyright','credits' or 'license' for more information
IPython 7.16.1 -- An enhanced Interactive Python. Type '?' for help.
In [1]: x = 1                                                                                                                                                                   
In [2]: y = 2                                                                                                                                                                   
In [3]: print(x,y)

来自ipython --help：

--nosep
    Eliminate all spacing between prompts.

也可以通过设置以下配置选项来实现此行为：

c.InteractiveShell.separate_in = ''
