blender python How to know where to look?

A lot of the time I"ll get error in syntax for parameters

Recently bmesh is confusing also

Unfortunately there’s no ‘man’ command to help in python so I’m wondering,

What steps do experienced programmers go through outside of asking for help?

The api is available, sure. But even that is more of a hit and miss than
shooting fish in a barrel.

Anyway, later.

For the BGE the api is enough, though a link to KX_Object and KX_Scene would be good. For the addons the API in not very clear, I prefer to look at the code of other addons that implement something similar to what I want to. By the way, I always use this website, building the API yourself is a nightmare.
