Is it possible to decompile a compiled .pyc file into a .py file?

问题

Is it possible to get some information out of the .pyc file that is generated from a .py file?

回答1:

Uncompyle6 works for Python 3.x and 2.7 - recommended option as it's most recent tool, aiming to unify earlier forks and focusing on automated testing. The GitHub page has more details.

The older Uncompyle2 supports Python 2.7 only. This worked well for me some time ago to decompile the .pyc bytecode into .py, whereas unpyclib crashed with an exception.

回答2:

Yes, you can get it with unpyclib that can be found on pypi.

$ pip install unpyclib

Than you can decompile your .pyc file

$ python -m unpyclib.application -Dq path/to/file.pyc

You may try Easy Python Decompiler. It's based on Decompyle++ and Uncompyle2. It's supports decompiling python versions 1.0-3.3

Note: I am the author of the above tool.

回答4:

Decompyle++ (pycdc) was the only one that worked for me: https://github.com/zrax/pycdc

was suggested in Decompile Python 2.7 .pyc

回答5:

Yes, it is possible.

There is a perfect open-source Python (.PYC) decompiler, called Decompyle++ https://github.com/zrax/pycdc/

Decompyle++ aims to translate compiled Python byte-code back into valid and human-readable Python source code. While other projects have achieved this with varied success, Decompyle++ is unique in that it seeks to support byte-code from any version of Python.
