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 (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

Building Decompyle++

  • Generate a project or makefile with CMake (See CMake's documentation for details)
  • Build the generated project or makefile
    • For projects (e.g. MSVC), open the generated project file and build it
    • For makefiles, just run make
    • To run tests (on *nix or MSYS), run make test

Usage

To run pycdas, the PYC Disassembler: ./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.
