Python!

As a Python IDE I am using Oepe Eclipse 3.6

An excellent tutorial

The entire Python Standard Library

and the language specs

It looks like I will do a lot of WLST/Python... I used to do all my WebLogic monitoring using Java/JMX but it's way too heavy. I love Java but you must be pragmatic.
Python “cheat sheet” - https://www.pcwdld.com/python-cheat-sheet - it’s a quick reference to Python that I think could be useful.
It’s not a cheat sheet in the traditional sense as it’s more about helping someone to get started with Python and then providing some shortcuts to make life easier.
