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.
