I first thought that it just returns numbers and you can do a lot of stuff with those numbers but now I am seeing that it is being used to run a loop a specific number of times. It's just not making sense to me why this works, like I can't intuitively understand it.
Tho I have started using in my code, an explanation on why it was developed this way would help.

You can think of range as returning a sequence of numbers. Since we use the syntax for in : to loop or iterate over a sequence, naturally we can put a range as the sequence. Does that help?

Python range() Function
The range() function can be called in a few different ways shown below (the range feature is implemented as a class, but it's simplest to think of it as a function). The most common form is range(n), given integer n returns a numeric series starting with 0 and extending up to but not including n, e.g. range(6) returns 0, 1, 2, 3, 4, 5. With Python's zero-based indexing, the contents of a string length 6, are at index numbers 0..5, so range(6) will produce exactly the index numbers for a string length 6, like this:

r/learnpython on Reddit: Can someone explain how range() works?
March 9, 2024 -
I've been using range() in for loops and thought range() simply returns a list, tuple or set containing a sequence of numbers. But when I tried print(x) where x = range(5), It simply gave out range(0, 5). I thought the output would be something like: [0, 1, 2, 3, 4].
My reason for thinking like that is because if I were to put a variable x (where x = range(5)) in a for loop, the for loop behaves exactly as if x = [0, 1, 2, 3, 4]. So, why does the range() behave differently if I use it outside a for loop.
I hope my question makes sense. Thank you in advance.
Edit: Thank you everyone. Your answers cleared up my confusion.

It used to work that way, in Python 2. But it was pretty inefficient; if you did range(1000000) it would have to create a list with a million numbers. So in Python 3 it was changed to be lazy. It's now similar to a generator, in that you can create an iterator from it which will give the next number each time you call it: x = range(10) it = iter(x) next(it) # 0 next(it) # 1 etc. Note that this is exactly what happens behind the scenes when you put anything into a for loop. It's a bit cleverer than a standard generator though as it also has comparison operators so you can do things like if 3 in range(1, 10).
