Indentation

  • Python Indentations (Exc 2)                                                                                           
    Where in other programming languages the indentation in code is for readability only, in Python the indentation is very important.
    Python uses indentation to indicate a block of code.

Chapter 1 | Python, class intro

Class

  • 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.

Chapter 1 | Python, class intro

Create a Class

To create a class, use the keyword class:

Example

Create a class named Snake, with a property named name

Chapter 1 | Python, class intro

The __init__() Function

Use the __init__() function to assign values to object properties, or other operations that are necessary to do when the object is being created.
