How to write return type of class instance in function python

Certainly! In Python, you can define a class and create instances of that class. When you have a function that operates on an instance of the class, you might want to specify the return type of that function to indicate what type of object it will return. This can be done using type hints.
Let's create a simple tutorial with an example to illustrate how to write the return type of a class instance in a function in Python.
In this example, we have a Dog class with a constructor (__init__), a method that returns a string (bark), and a method that doesn't return anything (celebrate_birthday).
Here, we define a function get_dog_info that takes a Dog instance as an argument and returns a string. We use type hints to indicate that the function returns a string.
In this step, we create an instance of the Dog class named my_dog and then call the get_dog_info function with my_dog as an argument. The result is printed, showing the dog's name and age.
When you run the code, you should see output like this:
In this tutorial, we've demonstrated how to write the return type of a class instance in a function using type hints in Python. This practice can enhance code readability and help developers understand the expected types when working with functions and class instances.
