Make a Class Object Behave Like a Function
If you want to make a class object callable, i.e., behave like a function, you can do so by defining the __𝐜𝐚𝐥𝐥__ method.
This method allows you to define the behavior of the object when it is invoked like a function.
This can have many advantages. For instance, it allows us to implement objects that can be used in a flexible and intuitive way. What's more, the familiar function-call syntax, at times, can make your code more readable.
Lastly, it allows you to use a class object in contexts where a callable is expected. Using a class as a decorator, for instance.
