Python: Find the positions of all uppercase vowels (not counting Y) in even indices

Python Programming Puzzles: Exercise-33 with Solution

Write a Python program to find the positions of all uppercase vowels (not counting Y) in even indices of a given string.

From Wikipedia:
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity. There are six vowels in the English language: a, e, i, o, u and sometimes y.

Input:
w3rEsOUrcE
Output:
[6]

Input: 
AEIOUYW 

Output:
[0, 2, 4]

Sample Solution:

Python Code:

# Define a function named 'test' that takes a string 'strs' as input
def test(strs):
    # Use a list comprehension to generate a list of indices for uppercase vowels (excluding 'Y') at even indices
    return [i for i, c in enumerate(strs) if i % 2 == 0 and c in "AEIOU"]

# Assign a specific string 'strs' to the variable
strs = "w3rEsOUrcE "

# Print a message indicating the operation to be performed
print("Original List:", strs)

# Print the original string
print("Positions of all uppercase vowels (not counting Y) in even indices:")
# Print the result of the test function applied to the 'strs' string
print(test(strs))

# Assign another specific string 'strs' to the variable
strs = "AEIOUYW "

# Print a message indicating the operation to be performed
print("\nOriginal List:", strs)

# Print the original string
print("Positions of all uppercase vowels (not counting Y) in even indices:")
# Print the result of the test function applied to the 'strs' string
print(test(strs))

Sample Output:

Original List: w3rEsOUrcE 
Positions of all uppercase vowels (not counting Y) in even indices:
[6]

Original List: AEIOUYW 
Positions of all uppercase vowels (not counting Y) in even indices:
[0, 2, 4]
