How to count the numbers of vowels and consonants in a sentence in python

This program prompts the user to input a phrase, then counts the number of vowels and consonants present in that phrase, ignoring uppercase letters and considering only alphabetical characters.

def count_vowels_consonants(phrase):
    vowels = 0
    consonants = 0
    # Converting the phrase to lowercase for easier comparison
    phrase = phrase.lower()
    # Defining a list of vowels
    vowels_list = ['a', 'e', 'i', 'o', 'u']
    # Iterating over each character in the phrase
    for character in phrase:
        # Checking if the character is a letter
        if character.isalpha():
            # Checking if the character is a vowel
            if character in vowels_list:
                vowels += 1
            else:
                consonants += 1
    return vowels, consonants

# Asking the user to input a phrase
user_phrase = input("Enter a phrase: ")
# Calling the function and storing the result
num_vowels, num_consonants = count_vowels_consonants(user_phrase)
# Displaying the results
print("Number of vowels:", num_vowels)
print("Number of consonants:", num_consonants)
