How to use Python variables in Google Colab terminal command?

Question

I have a cell with this content:

import os
os.mkdir(\'123\')
name = \'123\'
!rm -r name

I want to pass the value of the variable name

Answer 1

Try $. It will substitute the python variable.

!rm -r $name

You may need to use $name\.txt or {name}.txt in some cases.
