########## TYPE ##########

# type is one of the most fundamental and abstract terms of Python

# it is the foremost type that any class can be inherited from
# if we look for the type of class, type is returned

# in all other cases, it refers to the class that was used to instantiate the object
# it’s a general term describing the type/kind of any object

# it’s the name of a very handy Python function that returns the class information about the objects passed as arguments to that function

# it returns a new type object when type() is called with three arguments

# Python comes with a number of built-in types, like numbers, strings, lists, etc., that are used to build more complex types
# Creating a new class creates a new type of object, allowing new instances of that type to be made

# Information about an object’s class is contained in __class__
