Hey, welcome to a brand new day.

2
00:00:02,840 --> 00:00:09,290
Yesterday, you learned how to create arguments for your defined functions.

3
00:00:09,770 --> 00:00:16,670
You learn that you can have one argument such as here or more arguments divided by commas.

4
00:00:17,120 --> 00:00:25,010
So at this point, our program is able to get to dos by calling this function throughout the script,

5
00:00:25,020 --> 00:00:29,360
such as here, getting the to dos in the list through that function.

6
00:00:29,360 --> 00:00:36,920
But also the program is able to write to do in the text file in the to dos that text file using this

7
00:00:36,920 --> 00:00:38,150
right to this function.

8
00:00:39,570 --> 00:00:43,290
So function with one argument, function with two arguments.

9
00:00:43,290 --> 00:00:49,620
And another difference between these two functions is that this function here returns something and

10
00:00:49,620 --> 00:00:53,070
this function here doesn't return a value.

11
00:00:53,280 --> 00:01:00,090
So some functions output something and others simply do some actions when you call them.

12
00:01:00,090 --> 00:01:01,110
And that's all.

13
00:01:01,590 --> 00:01:06,780
For example, this function here writes the two dos in a text file, and that's all.

14
00:01:06,780 --> 00:01:08,370
It doesn't return anything.

15
00:01:09,300 --> 00:01:12,510
Today we're going to be looking deeper into functions.

16
00:01:12,510 --> 00:01:15,570
You're going to learn about default arguments.

17
00:01:15,570 --> 00:01:16,740
So ready?

18
00:01:16,800 --> 00:01:18,090
Let's see you in the next video.
