Welcome to Class Concepts: Object-Oriented Coding in Python.https://realpython.com/courses/python-class-object/continue/#t=0.67
My name is Christopher, and I will be your guide.https://realpython.com/courses/python-class-object/continue/#t=5.13
00:08https://realpython.com/courses/python-class-object/continue/#t=8.53
That title is a bit of a mouthful because this is a three-part course.https://realpython.com/courses/python-class-object/continue/#t=8.53
Releasing all three parts takes time,https://realpython.com/courses/python-class-object/continue/#t=13.17
so depending on when you’re doing this course,https://realpython.com/courses/python-class-object/continue/#t=15.6
the other two parts may still be in progress.https://realpython.com/courses/python-class-object/continue/#t=17.56
00:20https://realpython.com/courses/python-class-object/continue/#t=20.59
Links in the notes below will be provided to the other two parts as they becomehttps://realpython.com/courses/python-class-object/continue/#t=20.59
available.https://realpython.com/courses/python-class-object/continue/#t=24.58
The purpose of this course is to teach you about object-oriented coding inhttps://realpython.com/courses/python-class-object/continue/#t=26.28
Python.https://realpython.com/courses/python-class-object/continue/#t=29.62
00:30https://realpython.com/courses/python-class-object/continue/#t=30.64
The first part introduces you to the basic object-oriented coding structures,https://realpython.com/courses/python-class-object/continue/#t=30.64
like the class keyword, how you use it to write classes,https://realpython.com/courses/python-class-object/continue/#t=34.62
and how you associate attributes and methods (that’s OO speak for data andhttps://realpython.com/courses/python-class-object/continue/#t=37.6
operations) with the class.https://realpython.com/courses/python-class-object/continue/#t=42.58
00:45https://realpython.com/courses/python-class-object/continue/#t=45.41
Part two teaches you how to use inheritance,https://realpython.com/courses/python-class-object/continue/#t=45.41
a mechanism for structuring classes based on other classes.https://realpython.com/courses/python-class-object/continue/#t=48.1
This mechanism allows you to create hierarchies of classes to correspond to real-https://realpython.com/courses/python-class-object/continue/#t=51.77
world items, as well as providing a way of doing code reuse.https://realpython.com/courses/python-class-object/continue/#t=55.78
01:00https://realpython.com/courses/python-class-object/continue/#t=60.94
Parts one and two are the how, whereas part three is the why.https://realpython.com/courses/python-class-object/continue/#t=60.94
It concentrates on the design philosophy behind object-oriented coding andhttps://realpython.com/courses/python-class-object/continue/#t=65.79
introduces SOLID, an acronym that provides guidance on writing well-structuredhttps://realpython.com/courses/python-class-object/continue/#t=70.13
object-oriented software.https://realpython.com/courses/python-class-object/continue/#t=74.71
01:17https://realpython.com/courses/python-class-object/continue/#t=77.56
This is part one, Class Concepts,https://realpython.com/courses/python-class-object/continue/#t=77.56
and in it you will learn why you might want to write object-oriented code,https://realpython.com/courses/python-class-object/continue/#t=80.03
how to write classes, what attributes and methods are,https://realpython.com/courses/python-class-object/continue/#t=85.59
and how to use the descriptor protocol.https://realpython.com/courses/python-class-object/continue/#t=89.99
01:33https://realpython.com/courses/python-class-object/continue/#t=93.8
The code in this course was written with Python 3.11. Object-oriented codinghttps://realpython.com/courses/python-class-object/continue/#t=93.8
in Python has gone through some changes over the years,https://realpython.com/courses/python-class-object/continue/#t=98.58
and so the code presented here won’t work in Python 2 without some changes.https://realpython.com/courses/python-class-object/continue/#t=101.2
01:46https://realpython.com/courses/python-class-object/continue/#t=106.4
For the most part, I’ve stuck with general Python 3,https://realpython.com/courses/python-class-object/continue/#t=106.4
but there is the odd line here or there that uses newer language features.https://realpython.com/courses/python-class-object/continue/#t=109.44
I’ll point those out when they occur.https://realpython.com/courses/python-class-object/continue/#t=113.53
01:57https://realpython.com/courses/python-class-object/continue/#t=117.26
Python is a mixed bag and includes high-level concepts from a variety ofhttps://realpython.com/courses/python-class-object/continue/#t=117.26
different language styles. It has procedural codinghttps://realpython.com/courses/python-class-object/continue/#t=122.0
(that’s the straightforward scripting-type stuff), functional codinghttps://realpython.com/courses/python-class-object/continue/#t=125.3
(including patterns like lambdas, comprehensions, and map/reduce),https://realpython.com/courses/python-class-object/continue/#t=129.28
and what this course is about:https://realpython.com/courses/python-class-object/continue/#t=133.62
object-oriented coding. For all three of these,https://realpython.com/courses/python-class-object/continue/#t=135.5
Python takes a sort of loose approach.https://realpython.com/courses/python-class-object/continue/#t=138.64
02:21https://realpython.com/courses/python-class-object/continue/#t=141.1
You can take or leave these features as makes sense for the code you’re writing.https://realpython.com/courses/python-class-object/continue/#t=141.1
This is in contrast to languages like Java that are strictly object oriented,https://realpython.com/courses/python-class-object/continue/#t=145.86
where even "Hello, World" requires object-oriented concepts.https://realpython.com/courses/python-class-object/continue/#t=149.92
02:35https://realpython.com/courses/python-class-object/continue/#t=155.14
If you’ve never come across the term before,https://realpython.com/courses/python-class-object/continue/#t=155.14
object-oriented coding is an approach where you group data and operations onhttps://realpython.com/courses/python-class-object/continue/#t=157.1
that data together in a structure. In Python,https://realpython.com/courses/python-class-object/continue/#t=161.68
you use the class keyword to declare just such a structure.https://realpython.com/courses/python-class-object/continue/#t=165.59
02:48https://realpython.com/courses/python-class-object/continue/#t=168.99
The class is used to then create objects.https://realpython.com/courses/python-class-object/continue/#t=168.99
A piece of data on an object is called an attribute,https://realpython.com/courses/python-class-object/continue/#t=172.61
while the operations (like functions) are known as methods.https://realpython.com/courses/python-class-object/continue/#t=175.46
03:00https://realpython.com/courses/python-class-object/continue/#t=180.35
There are a variety of ways of declaring and using both attributes and methods,https://realpython.com/courses/python-class-object/continue/#t=180.35
each with different purposes.https://realpython.com/courses/python-class-object/continue/#t=184.45
This course will show you these differences and how to take advantage of them inhttps://realpython.com/courses/python-class-object/continue/#t=186.41
your code.https://realpython.com/courses/python-class-object/continue/#t=190.02
03:11https://realpython.com/courses/python-class-object/continue/#t=191.64
Your first foray into the object-oriented world covers why you might want tohttps://realpython.com/courses/python-class-object/continue/#t=191.64
foray into the object-oriented world. Foray is just a fun word to say.https://realpython.com/courses/python-class-object/continue/#t=195.58
