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
Generate a project or makefile with CMake (See CMake's documentation for details)
The following options can be passed to CMake to control debug features:
Produce debugging symbols
Enable block debugging output
Enable stack debugging output
Build the generated project or makefile
- For projects (e.g. MSVC), open the generated project file and build it
- For makefiles, just run
- To run tests (on *nix or MSYS), run
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.
Marshalled code objects:
Both tools support Python marshalled code objects, as output from
To use this feature, specify
-c -v <version> on the command line - the version must be specified as the objects themselves do not contain version metadata.
