Sum of All Odd numbers from 1 to N

# Print the Sum of all odd numbers from 1 to N

n = input("Enter a Integer number, bigger from 1: ")
n = int(n)

sum = 0

# Here using while loop:
#
# counter = 0
# while counter < n:
#     counter += 1
#     if counter % 2 != 0:
#         sum += counter

# The better way is with for loop:

for i in range(1, n + 1):
    if i % 2 != 0:
        sum += i

print('The Sum of all odd numbers from 1 to {0} is: {1}' .format(n, sum))
