00:00:01,001 --> 00:00:04,362
What makes a programmer a programmer?

3
00:00:04,363 --> 00:00:07,748
In other words, what are the things you need to

4
00:00:07,749 --> 00:00:12,080
know to be able to program any computer application?

5
00:00:12,610 --> 00:00:15,204
This is what I'm going to tell you in this video.

6
00:00:15,205 --> 00:00:16,628
There are three things you need to

7
00:00:16,629 --> 00:00:19,348
know to program to code any program.

8
00:00:19,349 --> 00:00:23,130
And the first is you need to know the syntax.

9
00:00:23,131 --> 00:00:25,372
For example, you need to know that to

10
00:00:25,373 --> 00:00:27,164
be able to print out some outputs, you

11
00:00:27,165 --> 00:00:29,602
need to use print followed by parentheses,

12
00:00:29,603 --> 00:00:33,298
and then you put the input inside those parentheses.

13
00:00:33,299 --> 00:00:35,852
So that is part of the syntax, knowing whether

14
00:00:35,853 --> 00:00:39,862
you want to use parentheses or commas, et cetera.

15
00:00:39,863 --> 00:00:41,120
That's the first thing.

16
00:00:41,121 --> 00:00:45,328
The next thing is, let's say we are building a program

17
00:00:45,329 --> 00:00:49,970
which calculates the average out of a series of values.

18
00:00:49,971 --> 00:00:54,148
Then you want to know what data type

19
00:00:54,149 --> 00:00:57,716
you need to use to represent this data.

20
00:00:57,717 --> 00:01:02,042
So for example, if you have the data as names

21
00:01:02,043 --> 00:01:06,152
of students followed by the grade of each student, then

22
00:01:06,153 --> 00:01:08,568
you know you need to use a dictionary because a

23
00:01:08,569 --> 00:01:11,694
dictionary is made of keys and values.

24
00:01:11,695 --> 00:01:13,278
So the correct data structure

25
00:01:13,279 --> 00:01:14,670
here would be a dictionary.

26
00:01:14,671 --> 00:01:18,558
But if you just had values without student names,

27
00:01:18,559 --> 00:01:22,252
then you'd think about a list because a list

28
00:01:22,253 --> 00:01:27,030
is just a series of items, values without keys.

29
00:01:27,610 --> 00:01:29,948
So data structures, you need to know data

30
00:01:29,949 --> 00:01:32,326
structures and you need to know the syntax.

31
00:01:32,327 --> 00:01:33,392
These are two things.

32
00:01:33,393 --> 00:01:37,622
The third thing is you need to know the algorithm

33
00:01:37,623 --> 00:01:41,062
you need to use to produce the expected output.

34
00:01:41,063 --> 00:01:43,910
So in this case, you should know the methods

35
00:01:43,911 --> 00:01:45,636
you can use or you should know how to

36
00:01:45,637 --> 00:01:48,378
create these methods if they don't exist.

37
00:01:48,379 --> 00:01:50,228
So in our example, you need to

38
00:01:50,229 --> 00:01:52,794
know how to create this average method.

39
00:01:52,795 --> 00:01:55,572
So these are the three things you

40
00:01:55,573 --> 00:01:59,360
need to know about making any program.

41
00:02:00,050 --> 00:02:02,610
These are the fundamentals.

42
00:02:02,611 --> 00:02:04,964
So I hope this makes it more clear,

43
00:02:04,965 --> 00:02:08,018
the way to programming and I'll

44
00:02:08,019 --> 00:02:10,000
talk to you in the next videos. See you.
