Python | Method Overloading
Like other languages (for example, method overloading in C++) do, python does not support method overloading by default. But there are different ways to achieve method overloading in Python.
The problem with method overloading in Python is that we may overload the methods but can only use the latest defined method.
In the above code, we have defined two product method, but we can only use the second product method, as python does not support method overloading. We may define many methods of the same name and different arguments, but we can only use the latest defined method. Calling the other method will produce an error. Like here calling will produce an error as the latest defined product method takes three arguments.
Thus, to overcome the above problem we can use different ways to achieve the method overloading.
Method 1 (Not The Most Efficient Method):
We can use the arguments to make the same function work differently i.e. as per the arguments.

The problem with above code is that makes code more complex with multiple if/else statement and is not the desired way to achieve the method overloading.
Method 2 (Efficient One):
By Using Multiple Dispatch Decorator
Multiple Dispatch Decorator Can be installed by:
pip3 install multipledispatch
In Backend, Dispatcher creates an object which stores different implementation and on runtime, it selects the appropriate method as the type and number of parameters passed.
