Swap cases in a string

Question

I\'m trying to solve this challenge in hackerrank, which asks to convert all lowercase letters to uppercase letters and vice versa.

I attempt it with the following code:

Answer 1

Python-3 in-built swapcase function.

def swap_case(s):
    return s.swapcase()

if __name__ == '__main__':
    s = input()
    result = swap_case(s)
    print(result)

Input:

"Pythonist 3"

Output:

"pYTHONIST 3"
