Code Explanation:
1. Class Definition
class A:
This line defines a class named A.
A class is a blueprint used to create objects.
2. Constructor Method
def __init__(self, x):
__init__ is the constructor.
It runs automatically when a new object of class A is created.
x is a parameter whose value is passed during object creation.
3. Instance Variable Assignment
self.x = x
self.x is an instance variable.
Each object gets its own copy of x.
4. Creating First Object
a = A(10)
An object a is created.
x is set to 10 for object a.
5. Creating Second Object
b = A(10)
Another object b is created.
Even though the value is the same (10), this is a different object in memory.
6. Equality Comparison (==)
a == b
== checks value equality.
Since class A does not define __eq__, Python compares object identity by default.
Because a and b are different objects, this returns False.
7. Identity Comparison (is)
a is b
is checks memory identity.
It returns True only if both variables refer to the same object.
Here, a and b refer to different objects → False.
8. Print Statement
print(a == b, a is b)
Output will be:
False False
