Hey, welcome to a new day on Python coding.

2
00:00:03,890 --> 00:00:07,550
Yesterday we worked on the get to this function.

3
00:00:07,550 --> 00:00:10,340
We added a default parameter.

4
00:00:10,760 --> 00:00:17,990
A default parameter means that when you call this function, for example, we call it here, down here.

5
00:00:18,840 --> 00:00:26,190
Then you don't need to provide an argument for that function because you already have a default value

6
00:00:26,190 --> 00:00:27,020
for the argument.

7
00:00:27,030 --> 00:00:34,410
However, you know that you can always provide a value if you don't want to have that default argument.

8
00:00:34,440 --> 00:00:36,980
Then we also learned about dog strings.

9
00:00:36,990 --> 00:00:45,360
This year is a docstring, so it's a string with triple quotes and in doc strings we write documentation

10
00:00:45,360 --> 00:00:47,670
for that particular function.

11
00:00:47,670 --> 00:00:54,060
So this should be some short text one or more sentences describing what this function does.

12
00:00:54,090 --> 00:01:00,450
This is good because later on when you return to your code as a programmer, you can read and you know

13
00:01:00,450 --> 00:01:02,400
exactly what this function does.

14
00:01:02,550 --> 00:01:09,660
This is also helpful for other programmers who are not the authors of the code, so they can also understand

15
00:01:09,660 --> 00:01:11,820
the code written by other people.

16
00:01:12,450 --> 00:01:15,570
So be a good citizen and write doc strings.

17
00:01:16,700 --> 00:01:20,240
And now we're ready to develop this program even further.

18
00:01:20,330 --> 00:01:24,530
So I'm excited to continue working with you and I'll see you in the next video.
