Write a short Python function num_vowels(text) that counts the number of vowels ina given character string
Question
Write a short Python function num_vowels(text) that counts the number of vowels in a given character string.
Solution
Sure, here is a simple Python function that counts the number of vowels in a given string:
def num_vowels(text):
count = 0
for char in text:
if char.lower() in 'aeiou':
count += 1
return count
This function works by iterating over each character in the input string. If the character is a vowel (we check this by seeing if the lowercase version of the character is in the string 'aeiou'), we increment a counter. At the end of the function, we return the counter.
