Python Classes and Objects
Python Classes/Objects
Python is an object oriented programming language.
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.
Create a Class
To create a class, use the keyword class:
Example
Create a class named MyClass, with a property named x:
class MyClass:
x = 5

Create Object
Now we can use the class named MyClass to create objects:
Example
Create an object named p1, and print the value of x:
p1 = MyClass()
print(p1.x)

Delete Objects
You can delete objects by using the del keyword:
Multiple Objects
You can create multiple objects from the same class:
Example
Create three objects from the MyClass class:
p1 = MyClass()
p2 = MyClass()
p3 = MyClass()
print(p1.x)
print(p2.x)
print(p3.x)

Note: Each object is independent and has its own copy of the class properties.
The pass Statement
class definitions cannot be empty, but if
you for some reason have a class definition with no content, put in the pass statement to avoid getting an error.
