1
00:00:00,000 --> 00:00:03,060
So this function here that we built in the

2
00:00:03,061 --> 00:00:06,300
previous lecture accepted an arbitrary number of

3
00:00:06,660 --> 00:00:10,920
non keyword arguments. For keyword arguments, you

4
00:00:10,921 --> 00:00:15,300
have to add another asterisk, two asterisks, and

5
00:00:15,301 --> 00:00:19,830
then pass a variable name, but kwargs is a

6
00:00:19,831 --> 00:00:22,530
convention. So please use that even though you don't

7
00:00:22,531 --> 00:00:27,990
have to, and then see what kwargs is, which

8
00:00:27,991 --> 00:00:33,420
stands for keyword args. If you try to call the

9
00:00:33,421 --> 00:00:36,600
function there, we will get an error because this

10
00:00:36,601 --> 00:00:40,050
is about a function with an arbitrary number of

11
00:00:40,051 --> 00:00:44,130
keyword arguments only. Therefore, all these

12
00:00:44,160 --> 00:00:47,880
arguments have to be named arguments, so keyword

13
00:00:47,910 --> 00:00:52,980
arguments, having the keyword arguments name, b,

14
00:00:53,010 --> 00:00:57,930
and c like that, and execute, and you get a

15
00:00:57,931 --> 00:01:02,520
dictionary. The dictionary will have items where

16
00:01:02,521 --> 00:01:06,240
each key will be the name of the arguments that

17
00:01:06,241 --> 00:01:09,600
you used when you called the function, and the

18
00:01:09,601 --> 00:01:11,940
value will be the value of that argument.

19
00:01:12,120 --> 00:01:14,910
Functions with an arbitrary number of keyword

20
00:01:14,940 --> 00:01:17,820
arguments are more readily used than functions

21
00:01:17,821 --> 00:01:20,250
with an arbitrary number of known keyword

22
00:01:20,251 --> 00:01:24,000
arguments, such as print function that I told you

23
00:01:24,001 --> 00:01:27,450
earlier, where you can just pass as many arguments

24
00:01:27,451 --> 00:01:30,480
without a keyword. So there you have it.

25
00:01:30,481 --> 00:01:34,400
