I'm looking at some tensorflow stuff and I understand for loops or atleast I think I do, however I came across for _ in range(20) and was wondering what is the meaning of the _ in this case. I am used to for x in range or for i in range stuff and understand those but haven't been able to understand what i've read on the underscore

When you are not interested in some values returned by a function we use underscore in place of variable name . Basically it means you are not interested in how many times the loop is run till now just that it should run some specific number of times overall.
