## What it is
decompyle3 is a native Python decompiler that translates Python bytecode (versions 3.7 and 3.8) back into equivalent Python source code. It is a refactored, stripped-down rework of uncompyle6 aimed at fixing long-standing control-flow reconstruction problems.

## Use cases
- decompile python 3.7 bytecode back to source
- recover lost python source code from .pyc files
- decompile python 3.8 bytecode
- analyze compiled python bytecode fragments
- reverse engineer python bytecode where uncompyle6 fails

## When to choose
- you need to decompile Python 3.7 or 3.8 bytecode
- uncompyle6 produces incorrect control flow for your bytecode
- you want a maintained fork focused on modern Python 3 bytecode

## When to avoid
- you need to decompile Python 2.x or older 3.x bytecode (use uncompyle6)
- you need to decompile Python 3.9+ bytecode
- you need a fully robust control-flow solution based on dominator analysis
