switching from notebook to pycharm

[enterthevoid22]

hi,
what would be a good way to become acquainted with pycharm ide for deep learning?

more specifically, i have some experience with deep learning packages (pytorch, tensorflow) and also generally writing python and matlab scripts.

but so far i worked with notebooks and the switch to pycharm is quite confusing.

i guess my question can thus become - what is a good way to learn all the terms used in building an actual software in python?
i'm stuck in figuring out what if __name__ = "main" means

maybe someone been in my position and can point me out to good tutorials

Maybe short explanation is good enough? __main__ — Top-level script environment from python.org
