Decompyle++
A Python Byte-code Disassembler/Decompiler
Decompyle++ aims to translate compiled Python byte-code back into valid and human-readable Python source code. While other projects have achieved this with varied success, Decompyle++ is unique in that it seeks to support byte-code from any version of Python.
Decompyle++ includes both a byte-code disassembler (pycdc.pycdas) and a decompiler (pycdc).
As the name implies, Decompyle++ is written in C++. If you wish to contribute, please fork us on github at https://github.com/zrax/pycdc

Usage:
To run pycdas, the PYC Disassembler: pycdc.pycdas [PATH TO PYC FILE] The byte-code disassembly is printed to stdout.

To run pycdc, the PYC Decompiler: pycdc [PATH TO PYC FILE] The decompiled Python source is printed to stdout. Any errors are printed to stderr.

Decompyle++ is the work of Michael Hansen and Darryl Pogue.
