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

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

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

Sample Solution-2:

Python Code:

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

# Define a function named 'test' that takes a string 'strs' as input
def test(strs):
    # Use the swapcase method to flip the case of characters and create a translation mapping
    # Replace vowels with characters two positions later in the alphabet
    translation_mapping = {
        ord('a'): ord('c'),
        ord('e'): ord('g'),
        ord('i'): ord('j'),
        ord('o'): ord('q'),
        ord('u'): ord('x'),
        ord('A'): ord('C'),
        ord('E'): ord('G'),
        ord('I'): ord('J'),
        ord('O'): ord('Q'),
        ord('U'): ord('X'),
        ord(' '): ord(' ')
    }

    # Apply the swapcase and translation mappings to the string
    result = strs.swapcase().translate(translation_mapping)

    # 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))
