2,649 PointsUnderstanding Class, object and Instance
So in the video.
she passed this code
below is the class created.
# class Car():
# pass
below is supposedly creating an object with class. the created object is my_car. this process is called instatiation.
#my_car = Car()
Does this mean, the variable "my_car" is the instance? as well as an object? is the variable an object also?
I am confused.

A class defined using
class Car:
pass
may be referred to as Car
. When parens are added, as in, Car()
, this causes the creation of an instance of the class. This object is usually assigned to a label, such as my_car
that points to the new created instance.
So "variables" are basically labels that point to objects. This is how objects are passed into functions. The label is passed to a function that, in turn, points it's local parameter label to the same object.
So my_car
is the label (aka variable) that points to an instance of Car
.
Going a bit further, once the class Car
has been defined, it is the label Car
that is pointed to the class.
Whoa, what's with all these labels? Also a good question. These label references to objects are all organized into namespaces, so that the scope of where they have meaning is well defined.
Post back if you have more questions. Good luck!
