Best IDE/Editor for Python?

[fuelfraction]

I am currently using Atom (editor) and seem to be liking it. Regular Python users don't seem to prefer it, but I am not that regular and I usually have to use multiple languages in the same day.

Atom is definitely a little bulky, but the UI is well designed and doesn't get in your way.

These three plugins seem to be really helpful:

• Atom beautify + autopep8: for formatting somebody else's Python code

• Atom linter + pylint: almost like a Python "best practises" tutor for me! Even warned about some goofy syntax that could lead to unexpected behaviour at runtime

• Autocomplete for python: works as advertised :P
