ah ! unfortunately there aren’t many ressources out there… I’m waiting for @mzjensen AU’s class submission to get hopefully accepted this year 
some forum threads on the subject :
Frankly, my recommendation is learn the basics of python and object oriented programming, then see the wealth of examples in this forum to see how to interact with the APIs. Paolo’s example cited in those links is particularly good ! At the beginning its overwhelming just to even navigate the API Reference Guide, but practice gets you there. Start simple and work yourself up.
