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}")

This lets you get the index of an element while iterating over a list. In other programming languages (C), you often use a for loop to get the index, where you use the length of the array and then get the index using that. That is not Pythonic, instead you should use enumerate().

Python uses 0-based indexing, meaning the first element has an index of 0; value: refers to the actual element at a given index. Let's apply enumerate() to our travel_list to print each city along with its index: 12345 travel_list = ['Monako', 'Luxemburg', 'Liverpool', 'Barcelona', 'Munchen'] # Printing all cities with their indexes for index, city in enumerate(travel_list): print(str(index) + ' ' + city)
