how to easily find my own way on blender's python?

blenderPython

Q: 

I never coded in python, but already in C++ and Java.
By "find my way" I mean a tip that will help me avoid creating many questions
AND also almost not have to study the documentation.


A:

Blender has a python console with auto completion (TAB key)!  
Starting on "bpy." we can navigate thru all sub data/variable/function structures!  
If you hit an iteration, as soon it suggests `['` just remove those chars and put a `.`, it may further expand into sub structures/vars etc!  

Knowing programming in general (logic and basic words), on the script editor, type what you think that may be correct, if it highlights it is correct ex.: `True`, and not `TRUE` nor `true`.  
I've created many simple scripts like that without having to read anything from the documentation.  

PS.: `def` is the function definition key like `def myFunction()`

Any more/better tips?
