Do you know the answer to this python quiz.

2
00:00:02,580 --> 00:00:07,380
In this example I've gotten a boon to computer and I'm gonna run Python 3.

3
00:00:07,560 --> 00:00:18,870
I'm going to say that A equals zero x A B equals zero x b c equals A plus B what is C equal to now.

4
00:00:19,260 --> 00:00:22,410
So when I press enter what is gonna be displayed.

5
00:00:22,410 --> 00:00:24,920
Can you answer this question.

6
00:00:24,960 --> 00:00:26,430
Notice the answer is 21.

7
00:00:26,450 --> 00:00:27,040
Why.

8
00:00:27,070 --> 00:00:38,320
Because 0 x means hexadecimal a in hex is 10 B in hex is 11 A plus B equals 21 in decimal.

9
00:00:38,430 --> 00:00:42,630
So don't forget 0 x means hexadecimal.

10
00:00:42,780 --> 00:00:45,970
You'll find something very similar on Cisco devices.

11
00:00:46,080 --> 00:00:51,570
So if you look at the config register of a Cisco device as an example you'll see something like 0 x

12
00:00:51,600 --> 00:00:56,970
2 1 0 2 indicating that the numbers that follow on hexadecimal.
