⚠️ USE THIS FILE IF YOU WANT TO DECOMPILE SINGLE ".PYC" TO ".PY".

• INSTALL PYTHON
• INSTALL UNCOMPLYLE -> pip install uncompyle6
• RUN THIS TO DECOMPILE SINGLE FILE FROM THE SOURCE FILE DIRECTORY -> python -m uncompyle6 -o . <fileName.pyc>

@praveenpgeb @ideamartin I believe you are both attempting to decompile only one file; in that case, follow this one.-> single .pyc decompile

a file created. but nothing compiled

I'm trying to decompile a single pyc file of 3.9 version
And I ran this command "python -m uncompyle6 -o main.pyc"
It is showing this error sir
ImportError: cannot import name 'iscode' from 'xdis'

Let me look into it over the weekend and get back to you.
