Goal

 

You are given a string and your task is to swap cases. 

In other words, convert all lowercase letters to uppercase letters and vice versa.

 

Solution

 

You can read one character in string and swap cases and return new string.

 

# sWAP cASE

def swap_case(s):
    
    new_s = ""
    
    for c in s:
        if c.isupper():
            new_s += c.lower()
            
        else:
            new_s += c.upper()
            
    return new_s


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