# Python: Find all words in a given string with n consonants

## Python Programming Puzzles: Exercise-43 with Solution

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.

Write a Python program to find all words in a given string with n consonants.

```Input: this is our time
Output:
Number of consonants: 3
Words in the said string with 3 consonants:
['this']

Number of consonants: 2
Words in the said string with 2 consonants:
['time']

Number of consonants: 1
Words in the said string with 1 consonants:
['is', 'our']
```

Sample Solution-1:

Python Code:

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

# Define a function named 'test' that takes a string 'strs' and an integer 'n' as inputs
def test(strs, n):
# List comprehension to filter words from the input string based on the number of consonants
return [w for w in strs.split() if sum([c not in "aeiou" for c in w.lower()]) == n]

# Assign a specific string 'strs' to the variable
strs = "this is our time"
# Print a message indicating the original string
print("Original string:", strs)
# Assign a specific value 'n' to the variable
n = 3
# Print a message indicating the number of consonants to be checked
print("Number of consonants:", n)
# Print a message indicating the operation to be performed
print("Words in the said string with", n, "consonants:")
# Print the result of the test function applied to 'strs' and 'n'
print(test(strs, n))

# Assign another specific value 'n' to the variable
n = 2
# Print a message indicating the number of consonants to be checked
print("\nNumber of consonants:", n)
# Print a message indicating the operation to be performed
print("Words in the said string with", n, "consonants:")
# Print the result of the test function applied to 'strs' and 'n'
print(test(strs, n))

# Assign another specific value 'n' to the variable
n = 1
# Print a message indicating the number of consonants to be checked
print("\nNumber of consonants:", n)
# Print a message indicating the operation to be performed
print("Words in the said string with", n, "consonants:")
# Print the result of the test function applied to 'strs' and 'n'
print(test(strs, n))
``````

Sample Output:

```Original string: this is our time
Number of consonants: 3
Words in the said string with 3 consonants:
['this']

Number of consonants: 2
Words in the said string with 2 consonants:
['time']

Number of consonants: 1
Words in the said string with 1 consonants:
['is', 'our']
```
