Welcome back everyone.

2

I wanted to take just a little bit of time to quickly discuss choosing Python 2 versus choosing Python

3

3.

4

It used to be that if you are a beginner and you were just learning Python it was actually a pretty

5

difficult decision to choose Python to versus Python 3 because many companies still had legacy Python

6

to code to be maintain.

7

However Python too was going to stop receiving security updates in the year 2020 and this course was

8

initially released teaching both versions of Python.

9

We taught both Python to Python 3 and the versions were similar enough that it was easy to learn both

10

simultaneously and technically it still is.

11

However now every major external Python package has been updated to support Python 3.

12

Basically 99 percent of the top 300 packages of Python that are external packages you can download fully

13

support Python 3 and some of them are even moving towards being exclusively for Python 3.

14

And these are packages such as Gengel for web development who will later in the future stop supporting

15

Python to because of this.

16

Now the course will focus solely on Python 3 and all the code all the notebooks and all the videos have

17

been updated to just focus purely on Python 3.

18

Now if need be going back to Python 2 syntax is a very easy jump.

19

Once you know Python 3 so you can go through this course learn the entirety of Python 3 the ins and

20

outs of the Python programming language and in case you get a job somewhere where they still have Python

21

2 legacy code.

22

Don't worry you're not going to be completely lost.

23

The languages are very very similar.

24

The versions of the languages are similar so you can easily jump from one to the other and I always

25

like to say that if you know Python 3 you basically already know Python too.

26

You just need to learn a couple of syntax changes in Python 3.

27

Really is the future of Python so that's where we focus on it for this course.

28

So just the short really quick summary based on three really is the future of Python.

29

So we're going to be using Python 3 exclusively for this course.

30

Now the old notebooks are available in case you need some Python to information.

31

But we're going to go ahead and get started by installing Python 3 and will be using Python 3 for the

32

rest of this course.

33

You have those old notebooks in case for some reason you need to reference legacy code.

34

Thanks and we'll see at the next lecture where we begin installing Python.
