## What it is
Decompyle++ is a C++ tool that translates compiled Python bytecode (.pyc files) back into readable Python source code. It includes pycdas, a bytecode disassembler, and pycdc, a decompiler, aiming to support bytecode from any Python version.

## Use cases
- decompile a .pyc file back to python source
- disassemble python bytecode
- recover lost python source code from compiled files
- analyze malware written in python
- inspect marshalled python code objects
- reverse engineer python binaries

## When to choose
- you need to decompile pyc files from many different Python versions
- you want a fast native C++ tool without Python dependencies
- you need both disassembly and decompilation of Python bytecode

## When to avoid
- you need perfect, guaranteed-accurate source recovery for modern Python versions
- you prefer a pure-Python tool you can extend easily
- you only need to disassemble bytecode for the current Python interpreter (use the stdlib dis module)

## Facets
- artifact type: cli-tool
