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
Try it Yourself »

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)
Try it Yourself »

Delete Objects

You can delete objects by using the del keyword:

Example

Delete the p1 object:

del p1
Try it Yourself »

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)
Try it Yourself »

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.

Example

class Person:
pass
