A simple program which checks Python source files for errors. Pyflakes analyzes programs and detects various errors. It works by parsing the source file, not importing it, so it is safe to use on modules with side effects. It's also much faster. It is available on PyPI and it supports ...
There were (and still are) a number of decompyle, uncompyle, uncompyle2, uncompyle3 forks around. Many of them come basically from the same code base, and (almost?) all of them are no longer actively maintained. One was really good at decompiling Python 1.5-2.3, another really good ...
