Let’s see the example to declare an instance variable in Python. Example: In the following example, we are creating two instance variablenameandagein theStudent...
Example:A Python class with instance variables class Person: def __init__(self, name, age): self.name = name self.age = age # Creating instances of the class person1 = Person("Taimi Dikla", 30) person2 = Person("Naoise Eunike", 25) ...
