What Are Objects And Classes?

The class keyword lets us define a class. We use it just like we do the def keyword for making functions. Class definitions are blocks like function definitions.

class NewClass:

Inside of the class, variables are called attributes.

class NewClass:
 name_attribute = "Kenneth"

And functions that are defined inside of a class are called methods.

class NewClass:
 name_attribute = "Kenneth"
 def name_method(self):
 return self.name_attribute

Whenever we call a class, it creates an instance. Each instance has full access to the all of the attributes and methods of the class.

new_instance = NewClass()
new_instance.name_method()
