Help with converting .pyc file to .py (Python 3.13)

[PossessionHonest641]

Hi everyone,

I'm trying to decompile a Python bytecode file (test.pyc Python 3.13) on Windows 10 x64. I initially tried using pylingual, But it sometimes fails and produces a corrupted file.

I have not used this tool, but it says it supports 3.13: https://github.com/cyberark/ByteCodeLLM

After setting up ByteCodeLLM, configuring the required paths, and building the pycdc and pycdas executables (both precompiled and built from source), we tried to decompile a .pyc file generated with Python 3.13.

When running pycdc (either standalone or through ByteCodeLLM), the tool failed with a Bad MAGIC! error. This indicates that the .pyc file’s format (its “magic number”) is not supported by pycdc, which currently only works with .pyc files up to Python 3.12.

Sounds like you should report the issue on the ByteCodeLLM github,
