- [Instructor] I've shown you previously

2
00:00:02,160 --> 00:00:06,730
how to take a string and turn
it into all lowercase letters

3
00:00:06,730 --> 00:00:08,560
by calling the lower method,

4
00:00:08,560 --> 00:00:10,520
and similarly there's an upper method

5
00:00:10,520 --> 00:00:13,250
to turn a string into
all uppercase letters.

6
00:00:13,250 --> 00:00:15,210
But there's a couple of additional methods

7
00:00:15,210 --> 00:00:17,240
that can come in handy as well.

8
00:00:17,240 --> 00:00:19,100
If you simply need to capitalize

9
00:00:19,100 --> 00:00:20,590
the first letter of a string

10
00:00:20,590 --> 00:00:23,200
you can call its capitalized method.

11
00:00:23,200 --> 00:00:26,610
In this case you can see
just the H gets capitalized.

12
00:00:26,610 --> 00:00:29,550
And separately if you
need to turn a string

13
00:00:29,550 --> 00:00:31,810
into what's known as title case,

14
00:00:31,810 --> 00:00:34,500
where each of the words is capitalized,

15
00:00:34,500 --> 00:00:37,210
you can call the title
method for that purpose.

16
00:00:37,210 --> 00:00:39,560
So in this case each of these four words

17
00:00:39,560 --> 00:00:43,130
will get capitalized and
there we have the title

00:00:43,130 --> 00:00:45,317
