Getting error while installing 'formatter' module

Question

I am trying to install formatter using,

pip install formatter

but it throws the following error,

Collecting formatter

I tried installing cStringIO but it throws another error,

ERROR: Could not find a version that satisfies the requirement cStringIO (from versions: none)
ERROR: No matching distribution found for cStringIO

Can anyone help me ?

This package was removed from python 3.10 (see latest doc from 3.9). You should update the code to not use the formatter module.
