Writing Python classes with multiple constructors can make your code more versatile and flexible, covering a wide range of use cases. Multiple constructors are a powerful feature that allows you to build instances of the underlying class using arguments of different types, a different number of arguments, or both, depending on your needs.
In this video course, you learned how to:
- Simulate multiple constructors using optional arguments and type checking
- Write multiple constructors using the built-in
- Overload your class constructors using the
You also learned how Python internally constructs instances of a given class and how some standard-library classes provide multiple constructors.
With this knowledge, now you can spice up your classes with multiple constructors, equipping them with several ways to tackle the instantiation process in Python.
