usage: unpy2exe [-h] [-o OUTPUT_DIR] [-p PYTHON_VERSION] filename

Extract pyc files from py2exe executable.

positional arguments:
  filename              The py2exe executable

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT_DIR, --output-dir OUTPUT_DIR
                        Output directory
  -p PYTHON_VERSION, --python-version PYTHON_VERSION
                        Python version for pyc
  -v, --verbose         Verbose output

You can install it from PyPI:

$ pip install unpy2exe

Install from source


  • pefile
  • six
  • argparse (Python < 2.7)

You can install dependencies through pip install -r requirements.txt


For .exe files generated with Python 2.x, you will need to run unpy2exe with Python 2.x; similarly, for Python 3.x .exe files, you will need to run unpy2exe with Python 3.x. Note the same unpy2exe source code works for both, but you will need to install the dependencies accordingly.

On the other hand, to be able to run the extracted .pyc file, you will need the same Python version used to generate the .exe, or at least the same major version (although it is highly probable you could still get some issues or crashes if the version doesn't match the original bytecode).
