Question
Predict the output of the following code snippetclass Area1: def init(self,feet): self.feet=feetclass Area2: def init(self,feet): self.feet=feeta1=Area1(12)a2=Area2(12)print("Total Area: ",a1+a2)
Solution
The code will raise a TypeError. This is because the '+' operator is not supported between instances of 'Area1' and 'Area2'. Python doesn't know how to add two objects of custom classes together unless it's explicitly defined how to do so.
If you want to be able to add two objects of these classes together, you would need to define an add method in your class. Here's an example of how you could do it:
class Area1:
def __init__(self,feet):
self.feet=feet
def __add__(self, other):
if isinstance(other, Area2):
return self.feet + other.feet
class Area2:
def __init__(self,feet):
self.feet=feet
a1=Area1(12)
a2=Area2(12)
print("Total Area: ",a1+a2)
In this code, the add method checks if the other object is an instance of Area2, and if it is, it adds the 'feet' attributes of the two objects together. Now, when you try to add a1 and a2, it will return 24.
