Hopefully this clarifies what exactly enumerate does:
>>> list(enumerate('abc'))
[(0, 'a'), (1, 'b'), (2, 'c')]
It just turns your list into a list of a pairs where each of your elements is joined with the index i.e. a with 0, b with 1 and c with 2.
That's not exactly true because it is an iterator rather than an actual list - so it provides you with values lazily when you wrap another iterator.
Looping over it is therefore the same as any other lists except usually it is done the following way:
for i, x in enumerate(xs)
You could still use:
for i in enumerate(xs)
but then just know that i is going to be a tuple with some int, and some object from xs.

Python enumerate(): Simplify Loops That Need Counters – Real Python
June 23, 2025 - Since the count is a standard Python integer, you can use it in many ways. ... Now that you’ve explored the basics of enumerate(), it’s time to practice using enumerate() with some real-world examples. Using conditional statements to process items can be a very powerful technique. Sometimes, you might need to perform an action on only the very first iteration of a loop, as shown in this example: ... >>> tasks_by_priority = ["Pay Rent", "Clean Dishes", "Buy Milk"] >>> for index, task in enumerate(tasks_by_priority): ...

October 14, 2024 - Without using enumerate, we would need a manual counter that makes the code less efficient. That’s why we could rely on enumerate looping through the index and values. Below is a code example of how to do that. data = ['apple', 'banana', 'cherry'] for i, fruit in enumerate(data): print(f"Index {i}: {fruit}")
