Feature Request: fixing indentation in an existing code

[OmerMaayan]

Hi,

It would be great if we could use this wonderful package to also fix indentation on a code we wrote beforehand.
It would be helpful for when I copy code from another file from another editor, or if I just installed your package and need to reformat everything in my code. Something like the 'Reformat' feature in PyCharm.

If it is already a feature then I have not found out how to use it and instructions will be very helpful.

Thank you!
Omer.
