Explanation:
1. Defining a Class
class A:
A new class named A is created.
Classes are blueprints for creating objects.
2. Creating a Property
x = property(lambda s: 5)
What is property()?
property() is a built-in Python function.
It is used to create getter, setter, and deleter methods.
Here, only a getter is provided.
Understanding the Lambda Function
lambda s: 5
This is equivalent to:
def get_x(s):
return 5
s represents the object instance (self).
Whenever x is accessed, Python calls this function.
It always returns 5.
So:
x = property(lambda s: 5)
means:
“Create a read-only property named x that always returns 5.”
3. Creating an Object and Accessing Property
print(A().x)
Step-by-step:
A() creates an object of class A.
.x accesses the property.
The lambda function runs and returns 5.
print() displays the result.
Output
5
