To find primes, why do i need to specify a range from 1 to the input number +1. Why +1

Question

num = int(input(""))
ListRange = list(range(1, num+1))

Why num+1, why is (1,num) not enough?

Answer 1

With range(start, stop) the last number is not included, so if you want to include it you need to add one to it.

For example, range(2, 6) will include only 2, 3, 4, and 5.

Answer 2

thank you very much
