# 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.

```Input: Hello
Output:
Hel

Input: Sandwhich
Output:
San

Input: Python
Output:
hon
```

Sample Solution:

Python Code:

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

# Define a function named 'test' that takes a string as input
def test(s):
cons = "bcdfghjklmnpqrstvwxz"  # Define a string containing consonants
vows = "aeiou"  # Define a string containing vowels

# Use a generator expression to find a vowel between two consonants in the string
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)

# Example 1
strs1 = "Hello"
print("Original string:", strs1)
print("Find a vowel between two consonants, contained in said string:")
print(test(strs1))

# Example 2
strs2 = "Sandwich"
print("\nOriginal string:", strs2)
print("Find a vowel between two consonants, contained in said string:")
print(test(strs2))

# Example 3
strs3 = "Python"
print("\nOriginal string:", strs3)
print("Find a vowel between two consonants, contained in said string:")
print(test(strs3))
``````

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
```
