1
00:00:00,000 --> 00:00:02,460
Let's take a quick look at the difference between Python

2
00:00:02,470 --> 00:00:03,480
2 and Python 3.

3
00:00:03,490 --> 00:00:06,060
So in this course, we're actually not going to be learning

4
00:00:06,070 --> 00:00:07,650
about Python 2 whatsoever.

5
00:00:07,660 --> 00:00:09,630
Python 2 is completely outdated.

6
00:00:09,640 --> 00:00:14,000
Actually, as of January 1st, 2020, Python 2 is outdated,

7
00:00:14,010 --> 00:00:16,910
and it is no longer receiving security updates whatsoever.

8
00:00:17,030 --> 00:00:20,340
So if you have by any chance a program that's using Python

9
00:00:20,340 --> 00:00:23,600
2 instead of Python 3, please upgrade it as it is now

10
00:00:23,600 --> 00:00:24,700
a security risk.

11
00:00:24,720 --> 00:00:27,330
And once again, we're just not going to be using Python 2

12
00:00:27,330 --> 00:00:28,740
at all because it is outdated,

13
00:00:28,750 --> 00:00:29,700
it's not supported,

14
00:00:29,710 --> 00:00:32,700
nobody's supposed to be using it anymore at all anyways.

15
00:00:32,979 --> 00:00:35,350
So in this course we're going to be learning Python 3,

16
00:00:35,350 --> 00:00:37,400
and to be more specific, we're going to be learning about

17
00:00:37,400 --> 00:00:40,400
Python 3.6, 3.7, 3.8,

18
00:00:40,540 --> 00:00:45,410
so newer versions of Python. Python 3, right now is the

19
00:00:45,420 --> 00:00:47,990
current future, which is a weird thing to say is the current

20
00:00:48,000 --> 00:00:51,700
future. Eventually, I'm sure Python 4 will be the actual

21
00:00:51,700 --> 00:00:55,500
future. But just once again, we're not using Python 2 whatsoever.

22
00:00:55,510 --> 00:00:59,310
And if you are enrolled in another course that is using Python

23
00:00:59,320 --> 00:01:01,770
2, you don't have to pay attention to any of that stuff

24
00:01:01,780 --> 00:01:05,040
because most of Python 3 is very similar to Python 2.

25
00:01:05,129 --> 00:01:05,879
Behind the scenes,

26
00:01:05,890 --> 00:01:07,110
there's some differences.

27
00:01:07,120 --> 00:01:09,690
But for the most part, you're not really going to see too

28
00:01:09,900 --> 00:01:10,900
many differences.

29
00:01:11,120 --> 00:01:14,570
Now, if in the future you're ever Googling a problem and

30
00:01:14,580 --> 00:01:17,180
you see this 'print' statement where it just says 'print', and

31
00:01:17,190 --> 00:01:19,820
then space and quotations, that is Python 2.

32
00:01:19,820 --> 00:01:22,190
That is how you immediately tell that someone is writing

33
00:01:22,200 --> 00:01:23,840
Python 2, but not Python 3.

34
00:01:23,930 --> 00:01:27,940
Python 3 looks like this 'print' statement where there is 'print',

35
00:01:27,950 --> 00:01:31,870
a bracket, and then quotations, and then some text inside of

36
00:01:31,880 --> 00:01:33,160
it. It has the brackets.

37
00:01:33,460 --> 00:01:37,510
So just a side by side comparison here we've got Python 2

38
00:01:37,520 --> 00:01:39,400
'print' statement, Python 3 'print' statement,

39
00:01:39,410 --> 00:01:41,890
and that is the quickest way to identify if someone is writing

40
00:01:41,900 --> 00:01:43,420
Python 2 or Python 3.

41
00:01:43,680 --> 00:01:47,880
There are some syntactical differences in Python 2 versus

42
00:01:47,880 --> 00:01:51,400
Python 3, such as using brackets or no brackets for the

43
00:01:51,400 --> 00:01:54,800
'print' statement, but for the most part, it is very, very similar.

44
00:01:54,800 --> 00:01:58,300
So when you learn Python 3, you are learning about 95% of

45
00:01:58,300 --> 00:02:00,300
Python 2 as well.
