Python: Find a string contains a vowel between two consonants, in a given string

Python Programming Puzzles: Exercise-73 with Solution

Write a Python program to find a substring in a given string that contains a vowel between two consonants.

From vocabulary.com:
A consonant is a speech sound that is not a vowel. It also refers to letters of the alphabet that represent those sounds: Z, B, T, G, and H are all consonants. Consonants are all the non-vowel sounds, or their corresponding letters: A, E, I, O, U and sometimes Y are not consonants.

def test(s):
    cons = "bcdfghjklmnpqrstvwxz"
    vows = "aeiou"
    return next(s[i - 1:i + 2] for i in range(1, len(s) - 1)
                if s[i].lower() in vows and s[i - 1].lower() in cons and s[i + 1].lower() in cons)
strs = "Hello"
print("Original string:",strs) 
print("Find a vowel between two consonants, contained in said string:")
print(test(strs))
strs = "Sandwhich"
print("\nOriginal string:",strs) 
print("Find a vowel between two consonants, contained in said string:")
print(test(strs))
strs = "Python"
print("\nOriginal string:",strs) 
print("Find a vowel between two consonants, contained in said string:")
print(test(strs)) 

Sample Output:

Original string: Hello
Find a vowel between two consonants, contained in said string:
Hel

Original string: Sandwhich
Find a vowel between two consonants, contained in said string:
San

Original string: Python
Find a vowel between two consonants, contained in said string:
hon
