PythonClasses 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 keywordclass:
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 »print(p1.x)
Delete Objects
You can delete objects by using thedel 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)
Try it Yourself »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 aclass definition with no content, put in thepass statement to avoid getting an error.
