Python: Find string s that, when case is flipped gives target where vowels are replaced by chars two later

Python Programming Puzzles: Exercise-40 with Solution

Write a Python program to find string s that, when case is flipped gives target where vowels are replaced by chars two later.

Input: Python 
Output:
pYTHQN

Input: aeiou
Output:
CGKQW

Input:  Hello, world!
Output:
hGLLQ, WQRLD!

Input: AEIOU 
Output:
cgkqw

def test(strs):
     return strs.translate({ord(c):ord(c)+2 for c in "aeiouAEIOU"}).swapcase()

strs = "Python" 
print("Original string:",strs)
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
print(test(strs))
strs = "aeiou" 
print("\nOriginal string:",strs)
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
print(test(strs))
strs = "Hello, world!" 
print("\nOriginal string:",strs)
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
print(test(strs))
strs = "AEIOU" 
print("\nOriginal string:",strs)
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
print(test(strs)) 

Sample Output:

Original string: Python
Find string s that, when case is flipped gives target where vowels are replaced by chars two later:
