Python

In this blog, we will learn about the use of the Polymorphic model of Django. Polymorphism: Polymorphism means the same function name (but different signatures) being uses for different types. Example: print(len("geeks")) output-:5 print(len([10, 20, 30])) output-:3 In this example, len is a function that is used for different types.Polymorphic model is also based on polymorphism. I did use the polymorphic model in many projects in excellence technologies. So for use Polymorphic model in Django, we will install dependencies first.
In this blog, we try something interesting. we can do one thing suppose we have a full working website then we want to use website login API in our API.

Should I spin up multiple threads?
Use multiple processes?
Use asynchronous programming?
