00:00:08,030 --> 00:00:12,700
Hello, I'm here to tell you about your end of course project.

2
00:00:12,700 --> 00:00:15,500
This course project that you're about to do,

3
00:00:15,500 --> 00:00:19,350
will cover a lot of the concepts that you've already covered in the course.

4
00:00:19,350 --> 00:00:22,095
You'll have to do a series of problems that are of

5
00:00:22,095 --> 00:00:24,990
varying types and covering varying concepts.

6
00:00:24,990 --> 00:00:27,945
But all of these problems that you'll be doing

7
00:00:27,945 --> 00:00:32,280
are the kind of programs that lots of people use in their real lives.

8
00:00:32,280 --> 00:00:36,120
Accumulation, gathering data together,

9
00:00:36,120 --> 00:00:38,670
changing what it looks like in this little program.

10
00:00:38,670 --> 00:00:42,740
These kinds of programs that you're about to write in your project are

11
00:00:42,740 --> 00:00:48,175
possibly very applicable to your everyday life in school or work or wherever.

12
00:00:48,175 --> 00:00:50,840
I want to remind you of some tips that may be

13
00:00:50,840 --> 00:00:53,120
useful as you start to work on this project.

14
00:00:53,120 --> 00:00:55,415
So, first of all, as you know,

15
00:00:55,415 --> 00:00:58,580
you should always change one thing in a program,

16
00:00:58,580 --> 00:01:02,410
predict what will happen when you eventually run that program,

17
00:01:02,410 --> 00:01:05,430
after changing this and then try it.

18
00:01:05,430 --> 00:01:08,000
That way, if you've only changed one thing,

19
00:01:08,000 --> 00:01:09,980
made a prediction and then tried it,

20
00:01:09,980 --> 00:01:13,190
you will know whether or not that worked,

21
00:01:13,190 --> 00:01:14,990
whether or not your prediction was right.

22
00:01:14,990 --> 00:01:19,475
You'll know if you have a good understanding of what you're working on in that moment.

23
00:01:19,475 --> 00:01:23,000
If you do a bunch of different things and then try it,

24
00:01:23,000 --> 00:01:25,670
you might have to dig through all those different things,

25
00:01:25,670 --> 00:01:28,820
to figure out what was good and what was not good and what you need to do

26
00:01:28,820 --> 00:01:33,100
to finish that program and get it to happen the way you want.

27
00:01:33,100 --> 00:01:34,960
Always change one thing,

28
00:01:34,960 --> 00:01:36,440
predict and then try it.

29
00:01:36,440 --> 00:01:40,190
I also want to remind you to use variable names that are clear to you.

30
00:01:40,190 --> 00:01:44,540
For instance, if you're using an accumulator pattern or any for-loop,

31
00:01:44,540 --> 00:01:47,690
you never want the iterator variable to be plural,

32
00:01:47,690 --> 00:01:51,155
because it's always going to be bound to one singular thing.

33
00:01:51,155 --> 00:01:53,990
You wouldn't want to plural variable name for

34
00:01:53,990 --> 00:01:56,060
a singular thing because that can be really

35
00:01:56,060 --> 00:01:58,790
confusing when you talk and think about your code.

36
00:01:58,790 --> 00:02:06,460
Similarly, I would advise you not to use the word L-I-S-T inside a variable name.

37
00:02:06,460 --> 00:02:08,800
It couldn't be a list because that's going to

38
00:02:08,800 --> 00:02:11,245
get confusing too when you read your code later.

39
00:02:11,245 --> 00:02:15,340
You'll think it's a list and then it will not be a list.

40
00:02:15,340 --> 00:02:18,290
All of these problems that you're about to do in this end of

41
00:02:18,290 --> 00:02:20,800
course project are different,

42
00:02:20,800 --> 00:02:22,270
but they're all similar patterns,

43
00:02:22,270 --> 00:02:24,700
problems that you've seen or done before.

44
00:02:24,700 --> 00:02:27,820
As you work on them I'd advise you to think about those

45
00:02:27,820 --> 00:02:30,790
and think about how they're similar to other stuff you've done.

46
00:02:30,790 --> 00:02:33,535
That will make it easier to progress on these.

47
00:02:33,535 --> 00:02:35,815
For each one, you should go through,

48
00:02:35,815 --> 00:02:38,605
make a step-by-step plan in words,

49
00:02:38,605 --> 00:02:41,860
no code at all for how you're going to solve the problem and

50
00:02:41,860 --> 00:02:46,955
then make sure that you can translate each of those pieces into code.

51
00:02:46,955 --> 00:02:50,080
For example, in an accumulation problem,

52
00:02:50,080 --> 00:02:53,180
you should talk through step-by-step as if you're talking to

53
00:02:53,180 --> 00:02:56,270
a robot or write down what each of those steps are,

54
00:02:56,270 --> 00:02:59,760
that needs to happen in that program, that little task.

55
00:02:59,760 --> 00:03:04,325
You can think step-by-step about how to translate each of those things into code.

56
00:03:04,325 --> 00:03:08,430
How can you translate your words into a program that will run and

57
00:03:08,430 --> 00:03:13,475
continue with changing one thing and then trying it to make sure that the code runs.

58
00:03:13,475 --> 00:03:16,100
Finally, if you see a problem,

59
00:03:16,100 --> 00:03:19,520
for example, maybe the last problem in this end of course project,

60
00:03:19,520 --> 00:03:24,110
where there is a complex task to do for each one of a set of things,

61
00:03:24,110 --> 00:03:28,085
do something with each string, for example.

62
00:03:28,085 --> 00:03:31,900
You should think about your plan for each individual task,

63
00:03:31,900 --> 00:03:37,570
say for doing that complex task for one string and make sure that that works,

64
00:03:37,570 --> 00:03:40,445
that everything is fine for just one string.

65
00:03:40,445 --> 00:03:46,310
If your code for doing the task one time with one string is successful,

66
00:03:46,310 --> 00:03:49,370
then you can move to building all of your code and

67
00:03:49,370 --> 00:03:52,730
putting it into a for- loop and implementing the full solution,

68
00:03:52,730 --> 00:03:56,090
so that all of your code is successful for that program.

69
00:03:56,090 --> 00:03:59,420
All of these problems are really useful for

70
00:03:59,420 --> 00:04:03,470
applications in almost everybody's everyday life in one way or another.

71
00:04:03,470 --> 00:04:08,220
I think they're fun. I hope you will enjoy yourself and I wish you good luck.
