Source formatting fixer?

[Bret]

Does anyone know of a package that can be used to "fix" bad formatting
in Python code? I don't mean actual errors, just instances where
someone did things that violate the style guide and render the code
harder to read.

If nothing exists, I'll start working on some sed scripts or something
to add spaces back in but I'm hoping someone out there has already
done something like this.

Thanks!

This may not be exactly what you want, but if you use Gedit there is a
handy reindent plugin.

sed???

Python has a range of tools for processing Python source code, which is
probably a far better solution than processing it as raw text.

Python already comes with a reindenter, see Tools\scripts\reindent.py
If you want to transform y= f ( x- 3 ) into y = f(x - 3) try PythonTidy
(search this same group for a link)

The thing is, I'm not so much trying to fix indentation issues as
spacing problems that affect readability but not program structure.
All the indentation is fine, this is more trying to change things
like:

if ((one==two)and(three==four)):
a=b+42
c=Classname (a,b)
print "Class %s created"%c.__name__

None of the above is wrong, it's just painfully ugly and given
Python's natural beauty, it seems really wrong all the same....

PythonTidy http://pypi.python.org/pypi/PythonTidy may help, altough I feel
it too aggressive sometimes.
Your example above is converted into this:

#!/usr/bin/python
# -*- coding: utf-8 -*-

if one == two and three == four:
a = b + 42
c = Classname(a, b)
print 'Class %s created' % c.__name__
