使用！将 shell 命令的输出分配给 .ipynb

Question

有没有办法把这个放在一条线上：

> ipython
Python 3.11.1 (main, Jan 24 2023, 17:02:06) [Clang 14.0.0 (clang-1400.0.29.202)]
Type 'copyright', 'credits' or 'license' for more information
IPython 8.8.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: l = ! ls

In [2]: l[:3]
Out[2]: ['___x.ipynb', 'data', 'e.txt']

In [3]: l = (! ls)[:3]
  Cell In[3], line 1
    l = (! ls)[:3]
         ^
SyntaxError: invalid syntax

?
