Initializer

A constructor is a special method that runs automatically when an object is created from a class. Its job is to set up the object’s initial state.

What a Constructor Does#

When you create an object, you often need to give it some starting values — a name, a score, a position. The constructor receives those values as arguments and stores them on the object.
