To understand better write it like this :-
N = int(input())
numbers = sum(range(N+1))
print(numbers)
Here, the range() function returns a consecutive sequence of numbers, starting from 0 by default, and increments by 1 (by default), and stops BEFORE a specified number(N).
write (N+1) to include the number aswell.
and the sum() function is adding up all the elements of the object returned by range() function.
