6,990 PointsIsn't enumerate a very inefficient way to get a simple loop counter? What if you're using a large dataset 10,000 times?
It just seems that calling a function during each loop iteration (a function that returns an object, no less) is too much when you could store a local variable and increment it?

Treehouse TeacherHey cassidyb !
To be honest, I haven't built anything using numbers like this yet so I started Googling
According to this Geeks for Geeks page, it's just adding a counter to an iterable.
According to this python-reference page, it's returning an enumerate object like you said.
This article has some alternatives if you find yourself in this situation and performance does in fact start getting noticeably worse.
