Ned Batchelder has posted a short script that will unmarshal a .pyc file and disassemble any code objects within, so you'll be able to see the Python bytecode. It looks like with newer versions of Python, you'll need to comment out the lines that set modtime and print it (but don't comment the line that sets moddate).

Turning that back into Python source would be somewhat more difficult, although theoretically possible. I assume all these programs that work for older versions of Python do that.

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  gt  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

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
