Don't use bare except, it catches all exceptions and makes debugging impossible. Also see my comment on the previous pull request.

Please stick to the PEP8 style guide.

Also as I said in the previous pull request, no need to download specifically Python 3.9.
Example readme with Markdown:

Important
Download Python 3.5 or newer from here and install it (tick the option "Add Python to PATH").
Open the command prompt and type: python -m pip install pymem pywin32

Run CS:GO before running this script. You will need to run this script with administrator privileges.

address = clientLpBaseOfDll + search(rb'\x83\xF8.\x8B\x45\x08\x0F',
You have a mistake at line 13, it needs to be client.lpBaseofDll not clientLpBaseOfDll.
