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)24Error in passing paramter as a2=Area2(12) Error in print("Total Area: ",a1+a2)Error in self.feet=feet in two classes
Solution
The code snippet you provided will result in a TypeError. This is because you are trying to add two objects of different classes (Area1 and Area2) together in the print statement. Python doesn't know how to add these two objects together.
Here is the error you would see:
TypeError: unsupported operand type(s) for +: 'Area1' and 'Area2'
If you want to add the 'feet' attributes of the two objects, you need to specifically tell Python how to do this. This can be done by defining a __add__ method in your classes. Here's how you could modify your classes to support this:
class Area1:
def __init__(self,feet):
self.feet=feet
def __add__(self, other):
return self.feet + other.feet
class Area2:
def __init__(self,feet):
self.feet=feet
def __add__(self, other):
return self.feet + other.feet
a1=Area1(12)
a2=Area2(12)
print("Total Area: ",a1.feet+a2.feet)
This will output: Total Area: 24
