Python Python Sequences Sequence Iteration Iterating with Enumerate

Is index a built in feature of Python?

How does the interpreter know what index is referring to? Is this a built in feature that automatically points to an object's position in a sequence?

No it's just a variable.

This line: index = 1, declares the variable and sets it to 1. So the first time through the loop, the printed string would be 1. roast beef. This line: index+=1 increments the index variable by 1, so the next time through the loop the printed string would be 2. cucumbers. And so on until we looped through all the items in the groceries list.

Got it, thanks!
