00:00:07,940 --> 00:00:11,625
Most weeks, our last lesson's going to be titled,

2
00:00:11,625 --> 00:00:13,245
The Way of the Programmer.

3
00:00:13,245 --> 00:00:16,560
These segments are not about how Python works,

4
00:00:16,560 --> 00:00:18,450
but about how you should work.

5
00:00:18,450 --> 00:00:20,400
Style tips for your codes,

6
00:00:20,400 --> 00:00:22,775
strategies for solving programming problems,

7
00:00:22,775 --> 00:00:25,860
habits, mindsets that will make it so that you can have

8
00:00:25,860 --> 00:00:29,370
fun even though it's hard work and sometimes frustrating.

9
00:00:29,370 --> 00:00:31,680
This week, we'll focus on debugging.

10
00:00:31,680 --> 00:00:34,920
Your programs are not going to always work the first time,

11
00:00:34,920 --> 00:00:37,860
in fact, they rarely will. You have to debug them.

12
00:00:37,860 --> 00:00:42,080
And debugging your code is a little bit like being a detective in

13
00:00:42,080 --> 00:00:47,245
a crime movie where you are also the criminal because you wrote the code.

14
00:00:47,245 --> 00:00:50,480
So are our learning objectives for this lesson,

15
00:00:50,480 --> 00:00:53,720
the end of it you should be able to distinguish between three types of errors;

16
00:00:53,720 --> 00:00:57,335
Syntax errors, Runtime errors and Semantic errors.

17
00:00:57,335 --> 00:01:00,830
You should develop a habit that when you get an error,

18
00:01:00,830 --> 00:01:04,010
you'll look at the error messages and start,

19
00:01:04,010 --> 00:01:09,120
you'll start to build a skill of interpreting those error messages.

20
00:01:09,250 --> 00:01:14,450
You will internalize a mantra of get something working and keep it working.

21
00:01:14,450 --> 00:01:17,980
Don't write big swaths of code before you test it.

22
00:01:17,980 --> 00:01:23,430
And you'll be able to recognize some common errors and how to fix them.
