## Can You Recover Python Code From .pyc Files?

Decompiling Pyc Files into Py Files: Is It Feasible?

Introduction

Python decompilation poses challenges, particularly in recent Python 3.x versions. This has led to the development of various tools with varying limitations and bugs. However, decompilation of Python 2.7 and earlier versions of Python 3.x should yield reasonable results, and even partial decompilation is preferable to losing essential code.

Recommended Tools

1. Uncompyle6:

   • Works up to Python 3.8.
   • Recommended as the initial approach due to its focus on unification and automated testing.
   • GitHub page: [Uncompyle6](https://github.com/rocky/uncompyle6)

2. Decompyle3:

   • A fork of Uncompyle6 for improved Python 3.7 compatibility.
   • Note: Located in the rocky/decompile3 repo (notice the different spelling).

Limitations

• Variable names and docstrings can be recovered, but comments will be lost.
• Certain code structures, especially those with unconventional control flow, or code written in recent Python 3.x versions, may not decompile successfully due to decompiler bugs.

Support for Recent Python Versions

Neither Uncompyle6 nor Decompyle3 supports Python versions 3.9 or above, and support for versions 3.7 or higher is limited. Continuously evolving optimizations in Python are hindering decompilation efforts, compounded by a lack of sufficient code contributions and sponsorship for these projects.

Supporting the Future

To foster the support and improvement of these decompilation tools:

• Report bugs to the relevant GitHub issues, after checking for duplicates.
• Sponsor these projects, especially if they have assisted you.

Additionally, implementing proper backup and version control practices can minimize the risk of code loss in the future.
