Python > Uncompyle2 - usage

Question

I'm trying to decompile some .pyc files - just need some basic data from them, I heard that best for it would be Uncompyle2,

so I installed Python27(Win), then I installed Uncompyle2 from https://github.com/wibiti/uncompyle2 - everything is ok so far, now I try to find out how to use it, readme says that I need to write uncompyle2 --h to get some more help, I'm getting after this "undefined" message, next I tried to import script via import uncompyle2 in interpreter, I think module is loaded(after I type uncompyle2 in interpreter it says, that it loaded functions from __init__) but still can't get any of it's functions to get work, if I try to do anything it says "syntax error"(even if I type everything just like from readme) and --h doesn't work either,

What I am doing wrong?

By the way, I tried to find some online converters, but since int's 2.6.4 python compiled files I can't find anything, that can work with it.

Answer 1

from IDLE

import uncompyle2
with open("uncompiled file.py", "wb") as fileobj:
    uncompyle2.uncompyle_file("afile.pyc", fileobj)

The result should be your uncompiled source code.

EDIT 2/15/18

for python 3 use uncompyle 6 and open the output file in "w" mode (not "wb")

import uncompyle6
with open("uncompiled file.py", "w") as fileobj:
    uncompyle6.uncompyle_file("afile.pyc", fileobj)

Answer 2

To run from your command line (PowerShell for example) you need to run the script uncompyle2 in Scripts, probably in C:\Python\Scripts if you installed Python to C:\Python. This will decompile the file somefile.pyc and create the file decompiled.py in c:\temp

PS C:\Python\Scripts> python .\uncompyle2 -o c:\temp\decompiled.py somefile.pyc

Answer 3

Just retried the version at https://github.com/wibiti/uncompyle2

But it wasn't getting imported. I had to search the library and found that it had been renamed... so this is the code that has worked for me:

import uncompyle6
with open("uncompiled file.py", "wb") as fileobj:
    uncompyle6.uncompyle_file("yourpycfile.pyc", fileobj)
