# 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 strings that, when case is flipped, give a target where vowels are replaced by characters two later.

```Input: Python
Output:
pYTHQN

Input: aeiou
Output:
CGKQW

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

Input: AEIOU
Output:
cgkqw
```

Sample Solution-1:

Python Code:

``````# License: https://bit.ly/3oLErEI

# Define a function named 'test' that takes a string 'strs' as input
def test(strs):
# Use the translate method to create a mapping for each vowel to the character two positions later
translation_mapping = {ord(c): ord(c) + 2 for c in "aeiouAEIOU"}

# Apply the translation mapping and swap the case of the characters in the string
result = strs.translate(translation_mapping).swapcase()

# Return the modified string
return result

# Assign a specific string 'strs' to the variable
strs = "Python"
# Print a message indicating the original string
print("Original string:", strs)
# Print a message indicating the operation to be performed
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
# Print the result of the test function applied to 'strs'
print(test(strs))

# Assign another specific string 'strs' to the variable
strs = "aeiou"
# Print a message indicating the original string
print("\nOriginal string:", strs)
# Print a message indicating the operation to be performed
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
# Print the result of the test function applied to 'strs'
print(test(strs))

# Assign another specific string 'strs' to the variable
strs = "Hello, world!"
# Print a message indicating the original string
print("\nOriginal string:", strs)
# Print a message indicating the operation to be performed
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
# Print the result of the test function applied to 'strs'
print(test(strs))

# Assign another specific string 'strs' to the variable
strs = "AEIOU"
# Print a message indicating the original string
print("\nOriginal string:", strs)
# Print a message indicating the operation to be performed
print("Find string s that, when case is flipped gives target where vowels are replaced by chars two later:")
# Print the result of the test function applied to 'strs'
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:
pYTHQN

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

Original string: Hello, world!
Find string s that, when case is flipped gives target where vowels are replaced by chars two later:
hGLLQ, WQRLD!

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

``````# License: https://bit.ly/3oLErEI
