uncompyle2 1.1

Python byte-code to source-code converter

A Python 2.7 byte-code decompiler, written in Python 2.7


'uncompyle2' converts Python byte-code back into equivalent Python
source. It accepts byte-code from Python version 2.7 only. Additionally,
it will only run on Python 2.7.

The generated source is very readable: docstrings, lists, tuples and
hashes get pretty-printed.

'uncompyle2' may also verify the equivalence of the generated source by
by compiling it and comparing both byte-codes.

'uncompyle2' is based on John Aycock's generic small languages compiler
'spark' ( and his prior work on
a tool called 'decompyle'. This tool has been vastly improved by
Hartmut Goebel ``_

Additional note (3 July 2004, Ben Burton):

This software is no longer available from the original website. It
has now become a commercial decompilation service, with no
software available for download.

Any developers seeking to make alterations or enhancements to this code
should therefore consider these debian packages an appropriate starting


* decompiles Python byte-code into equivalent Python source

* decompiles byte-code from Python version 2.7

* pretty-prints docstrings, hashes, lists and tuples

* reads directly from .pyc/.pyo files, bulk-decompile whole

* output may be written to file, a directory or to stdout

* option for including byte-code disassembly into generated source

For a list of changes please refer to the 'CHANGES' file.


uncompyle2 requires Python 2.7


You may either create a RPM and install this, or install directly from
the source distribution.

Creating RPMS:

python bdist_rpm

If you need to force the python interpreter to eg. pyton2:
python2 bdist_rpm --python=python2

Installation from the source distribution:

python install

To install to a user's home-dir:
python install --home=<dir>

To install to another prefix (eg. /usr/local)
python install --prefix=/usr/local

If you need to force the python interpreter to eg. pyton2:
python2 install

uncompyle2 -h prints short usage
uncompyle2 --help prints long usage
