ipython 不加新行

Question

考虑 ipython 回复：

$ 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]:

相比之下，考虑正常的python repl:

$ python
Python 3.6.8 (default, Aug  7 2019, 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
>>>

正如你所看到的，ipython repl 添加了很多不必要的（我认为）换行语句，而 python repl 则更加简洁。

有什么方法可以禁用这些新行吗？（请注意，我知道这一点：https://ipython.readthedocs.io/en/stable/config/details.html 可以更改提示中显示的内容。但是，我找不到禁用提示之间的新行的选项）

使用 --nosep 选项启动 ipython。

$ 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.

也可以通过设置此配置选项来实现此行为：

c.InteractiveShell.separate_in = ''
