# Almost everything in Python is an object, with its properties and methods.
#A Class is like an object constructor, or a "blueprint" for creating objects.

class simple_example:
    x = 10
    
# Use the class, or instantiate, to create objects of the class

new_obj = simple_example()
print(new_obj)

# This does not have much use, but shows how to create a simple object from a class
# All classes have a function called __init__(), which is always executed when the class is being initiated.
# Use the __init__() function to assign values to object properties, or other operations that are necessary to do when the object is being created:

# Classes can also contain Object Methods
