Summation

Write a program that finds the summation of every number from 1 to num. The number will always be a positive integer greater than 0.

For example:

summation(2) -> 3
1 + 2

summation(8) -> 36
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8

def summation(num):
    # first:
    return sum(i for i in range(num+1))

    # second:
#     total = 0
    
#     for i in range(num + 1):
#         total += i
        
#     return total
