Python Programming MOOC 2021 - More Loops - Flip the pairs

[Alicia Morillo]

Hello! I need help with this exercise because I can't find the solution :'(

Please write a program which asks the user to type in a number. The program then prints out all the positive integer values from 1 up to the number. However, the order of the numbers is changed so that each pair or numbers is flipped. That is, 2 comes before 1, 4 before 3 and so forth. See the examples below for details.

Please type in a number: 5 2 1 4 3 5

Please type in a number: 6 2 1 4 3 6 5 

My code has some mistakes because when the input is 5, I also print the number 6.

number = int(input("Please type in a number: "))

for i in range(1, number+1, 2):

    print(f'{i+1}', end='')

    print(f'{i}', end='')

Help!!!!! Thanks!

Correct answer:

num = int(input("Please type in a number: "))

for i in range(1, num+1, 2):

    if i < num:

        print(f'{i+1}')

    print(f'{i}')
