sWAP cASE
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.
For Example:
Www.HackerRank.com → wWW.hACKERrANK.COM
Pythonist 2 → pYTHONIST 2
Function Description
Complete the swap_case function in the editor below.
swap_case has the following parameters:
- string s: the string to modify
Returns
- string: the modified string
Input Format
A single line containing a string s.
Constraints

Sample Input 0
HackerRank.com presents "Pythonist 2".
Sample Output 0
hACKERrANK.COM PRESENTS "pYTHONIST 2".
문제해석
입력되는 string에서 대문자는 소문자로 소문자는 대문자로 각각 변경하여 출력하면 된다.
문제풀이
보통 lower(), upper() 이렇게 제공하는데, 파이썬에서는 친절하게도 swapcase()라는 함수를 제공한다.
def swap_case(s):
return s.swapcase()
if __name__ == '__main__':
s = raw_input()
result = swap_case(s)
print result
