Decompile Python 2.7 .pyc

UPDATE (2019-04-22) - It sounds like you want to use uncompyle6 nowadays rather than the answers I had mentioned originally.

This sounds like it works: http://code.google.com/p/unpyc/

Issue 8 says it supports 2.7: http://code.google.com/p/unpyc/updates/list

UPDATE (2013-09-03) - As noted in the comments and in other answers, you should look at https://github.com/wibiti/uncompyle2 or https://github.com/gstarnberger/uncompyle instead of unpyc.

Decompyle++ (pycdc) appears to work for a range of python versions: https://github.com/zrax/pycdc

For example:

git clone https://github.com/zrax/pycdc   
cd pycdc
make  
./bin/pycdc Example.pyc > Example.py

In case anyone is still struggling with this, as I was all morning today, I have found a solution that works for me:

Uncompyle

Installation instructions:

git clone https://github.com/gstarnberger/uncompyle.git
cd uncompyle/
sudo ./setup.py install

Once the program is installed (note: it will be installed to your system-wide-accessible Python packages, so it should be in your $PATH), you can recover your Python files like so:

uncompyler.py thank_goodness_this_still_exists.pyc > recovered_file.py

The decompiler adds some noise mostly in the form of comments, however I've found it to be surprisingly clean and faithful to my original code. You will have to remove a little line of text beginning with +++ near the end of the recovered file to be able to run your code.
