Well, most of the things you ask should be written as such, not written and
then beautified!

Your editor should support this.

Well... that's a matter of fact, not just style. Sometimes parentheses help
the reading; if a,b are not just plain names but somewhat complex
instructions, parentheses should stay.

Code should be written this way.

the += operator is syntactic sugar just to save time... if one doesn't use
it I don't think it's a matter of beauty.

what? No, I think you're missing the difference between 'is' and '=='. You
could say it the other way for None, True, False, e.g. if there's a 'a ==
None' it could be safely converted to 'a is None', but again: this should
be done while writing the code.

> break long lines (in a reasonable way)

well... this could be useful sometimes, but again... 'reason' is usually
something human beings should employ, and shouldn't be 'outsourced' to
computer programs.

That's impossibile! Python is dynamically typed! How could the 'beautifier'
understand what the 'string' name is bound to? It could be whatever object!

Those are editor tasks.

Get a good Editor or IDE. You haven't told us what OS are you on. If you're
on Windows, UltraEdit can do most of the things you'd like. And don't rely
on a software to correct human behaviours ^_^.
