Question
Vowels and Consonants
Write a program with a function that accepts a string as an argument and returns the number of vowels that the string contains. The application should have another function that accepts a string as an argument and returns the number of consonants that the string contains. The application should let the user enter a string and should display the number of vowels and the number of consonants it contains.
Answer
Vowels and Consonants Program code:
#Method countVowels
def countVowels(string):
vowels = 'aeiouAEIOU'
vowel_count = 0
# Iterate over each character in the string
for char in string:
# Check if the character is a vowel
if char in vowels:
vowel_count += 1
return vowel_count
#Method countConsonants
def countConsonants(string):
consonants = 'bcdfghjklmnpqrstvwxyzBCDFGHJKLMNPQRSTVWXYZ'
consonant_count = 0
# Iterate over each character in the string
for char in string:
# Check if the character is a consonant
if char in consonants:
consonant_count += 1
return consonant_count
# Promt and read the string from the user
string = input("Enter a string: ")
# Call the count_vowels and count_consonants functions
vowel_count = countVowels(string)
consonant_count = countConsonants(string)
# Display the counts of vowels and consonants
print("Number of vowels:", vowel_count)
print("Number of consonants:", consonant_count)
Executed Output:
Enter a string: Hello Python
Number of vowels: 3
Number of consonants: 8
