Code Explanation:
1. Defining the Class
class Word:
Creates a class named Word.
This class can contain methods to perform operations on words or strings.
2. Defining a Method
def vowels(self, word):
Defines a method named vowels inside the Word class.
self refers to the instance of the class calling the method.
word is the string parameter for which we want to count vowels.
3. Initializing a Counter
count = 0
Initializes a variable count to 0.
This variable will keep track of the number of vowels found in the word.
4. Looping Through Each Character
for ch in word:
Iterates over each character ch in the input string word.
5. Checking if Character is a Vowel
if ch.lower() in "aeiou":
count += 1
ch.lower() converts the character to lowercase, so the check is case-insensitive.
If the character is in "aeiou" → it is a vowel → increment count by 1.
Let’s trace for "Object":
Character ch.lower() Vowel? count after step
O o Yes 1
b b No 1
j j No 1
e e Yes 2
c c No 2
t t No 2
6. Returning the Count
return count
Returns the total number of vowels found in the word.
7. Creating an Object
w = Word()
Creates an instance w of the Word class.
This object can now call the vowels() method.
8. Calling the Method and Printing
print(w.vowels("Object"))
Calls the vowels() method on the object w with "Object" as input.
Returns 2 → number of vowels (O and e).
print() displays the result.
Final Output
