1
00:00:00,000 --> 00:00:00,500


2
00:00:00,500 --> 00:00:02,700
SPEAKER: For quote we have three to-dos.

3
00:00:02,700 --> 00:00:06,270
We want to display the form for
the user to look up the stock.

4
00:00:06,270 --> 00:00:08,970
We want to then retrieve
the quote for that stock.

5
00:00:08,970 --> 00:00:12,990
And finally, display the
current price for that stock.

6
00:00:12,990 --> 00:00:16,320
So for the display form,
let's make another template.

7
00:00:16,320 --> 00:00:19,980
For instance, it can
be called quote.HTML.

8
00:00:19,980 --> 00:00:22,110
So this will include a
form that allows them

9
00:00:22,110 --> 00:00:26,170
to input the symbol of the
stock the user wants to look up.

10
00:00:26,170 --> 00:00:29,020
Once we have that symbol,
let's use the VLOOKUP function.

11
00:00:29,020 --> 00:00:32,080
Remember the implementation
is found in helpers.py.

12
00:00:32,080 --> 00:00:37,580
That will return a dict with the
name, price, and symbol of that stock.

13
00:00:37,580 --> 00:00:41,440
Now that we know how much the
stock costs, let's tell the user.

14
00:00:41,440 --> 00:00:44,960
To display this information
let's create another template.

15
00:00:44,960 --> 00:00:48,730
The reason for this is that the
quote.HTML template that we've already

16
00:00:48,730 --> 00:00:52,780
made includes the form submission,
whereas this information is

17
00:00:52,780 --> 00:00:54,260
going to be different.

18
00:00:54,260 --> 00:00:57,040
So we'll only display
the stock information

19
00:00:57,040 --> 00:00:59,420
if the stock is, after all, valid.

20
00:00:59,420 --> 00:01:01,720
Otherwise, include another apology.

21
00:01:01,720 --> 00:01:07,210
So how do we pass on information and
values that we have from a Python file

22
00:01:07,210 --> 00:01:09,040
into HTML?

23
00:01:09,040 --> 00:01:14,090
Well, when we call render a template
we're allowed to pass in values.

24
00:01:14,090 --> 00:01:19,180
So if I had a template called
hello.HTML within my main blog,

25
00:01:19,180 --> 00:01:22,330
then I could have a paragraph
that simply said, "hello,"

26
00:01:22,330 --> 00:01:24,970
and then had a placeholder for a name.

27
00:01:24,970 --> 00:01:30,140
Note these two curly braces allow
me to reference a Python value.

28
00:01:30,140 --> 00:01:35,860
So within application.py, I
would include a route to hello,

29
00:01:35,860 --> 00:01:40,720
and I would return render
template, hello.HTML, and passing

30
00:01:40,720 --> 00:01:42,710
in the name "World."

31
00:01:42,710 --> 00:01:44,320
So what would I see in HTML?

32
00:01:44,320 --> 00:01:46,940
Well, it would replace
name with "World!"

33
00:01:46,940 --> 00:01:51,520
So my page would say, "Hello, World!
" Now that we've displayed the quote,

34
00:01:51,520 --> 00:01:55,660
let's go on and allow them to buy it
if they decide that that stock is worth

35
00:01:55,660 --> 00:01:57,210
it.

36
00:01:57,210 --> 00:01:58,026
