What’s the best Python IDE for beginners?

What I’m looking for:

1. Good autocomplete tools and maybe debugging
2. Short term use, therefore low cost
3. Modern interface

A lot of people on Quora say  Pycharm is really good ($89 a year for individual; $199 for organization; monthly plans $9).

As an iOS developer, I was interested to learn that Xcode works with Python too. You just have to do some configuration.

As a beginner with lower requirements, it seems like Komodo Edit (free) or a text editor like Sublime Text ($70) or Textmate (free)  would also work.

Order for trying

1. Komodo Edit
2. Sublime Text or Textmate
3. Pycharm
4. Xcode
