Python Programming: Lesson 35 - String Representation of an Object
PLEASE SUBSCRIBE!!!
In the previous lesson ( • Python Programming: Lesson 34 - Inher... ), we studied inheritance as a fundamental of object-oriented programming. Here, we use the _str_ function to implement a string representation of any object.
def __str__(self):
This function defines what it means to print an instance of a class
This is nice if we want a clean string representation that shows the values of
the instance variables for a particular object. It's up to us how we write it!
return self.name + " is " + self.age + " years old"
