Challenge #14 - sWAP cASE

 Approach 1 :

def swap_cases(s)
new_str = ''
for i in s :
    if i.islower():
        new_str += i.upper()
    else :
        new_str += i.lower()
return new_str

if __name__ == "__main__":
    s = input()
    print(swap_cases(s))

Apporach 2 :

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

if __name__ == "__main__":
    s = input()
    print(swap_cases(s))
