Understanding Callables in python ?
Problem:You want to understand what callables are in Python and how various objects, including functions, methods, and instances, can be invoked as if they were functions.Solution: In Python, a callable is an object that can be called like a function using the ( ) operator. Here are different types of callables:
Functions: Regular functions defined with the def keyword or lam bda functions created with lambda.
Methods: Functions defined within classes that can be called on instances of those classes.
Classes: You can call a class to create an instance of that class, for example, my_instance = MyClass().
Callable Objects: Some objects define a special method _call_ that allows them to be called as if they were functions. You can create callable instances of a class by defining a _call_ method.
Built-in Functions: Python's built-in functions like len(), print(), and open() are callables.
Callable Instances: Objects can be made callable by defining the _call_ method, enabling you to create instances that act like functions.
