Using Python Class Constructors (Summary)

Now you know how Python class constructors allow you to instantiate classes, so you can create concrete and ready-to-use objects in your code. In Python, class constructors internally trigger the instantiation or construction process, which goes through instance creation and instance initialization. These steps are driven by the .__new__() and .__init__() special methods.

By learning about Python’s class constructors, the instantiation process, and the .__new__() and .__init__() methods, you can now manage how your custom classes construct new instances.

In this video course, you learned:

  • How Python’s instantiation process works internally
  • How your own .__init__() methods help you customize object initialization
  • How overriding the .__new__() method allows for custom object creation

Now you’re ready to take advantage of this knowledge to fine-tune your class constructors and take full control over instance creation and initialization in your object-oriented programming adventure with Python.

The last 2 parts were hard to understand for me, I think giving some real life exemples could help.

@Cenk T - can you give me a bit more information about the confusion you’re having, and hopefully I’ll be able to help out?

@Younes - Are you talking about the Single Instance and Emulating namedtuple sections?
