All right, let's do the top scores.
0:02
Over here in Postman we get, these are the top scores
0:08
as HTML, not what we want.
0:10
So let's write these.
0:11
Go ahead and put a little bit of code here like before
0:14
We're going to go get all the players
0:15
and we're going to compute the wins.
0:17
We're going to store the player as JSON
0:20
and the score as the number of wins for that player.
0:23
So this is a list of dictionaries that contains
0:28
two things, the player and the score.
0:30
And there's no particular order to this,
0:32
but because it contains the score,
0:35
what we can do is simply go down here
0:36
and say we're going to sort, give it the function
0:39
that's going to say, go get the score for each one
0:42
and sort in reverse order with that negative there.
0:46
Okay?
0:47
So now we want a return flask.jsonify.
0:51
Do you want to return all of them?
0:52
What if there's 100,000 players?
0:54
Not a great idea, so let's just return the top 10,
0:57
and we can use a slice.
0:59
So it'll construct here, if we haven't talked
1:01
about it previously we'll say,
1:02
given a large array, return either
1:04
the whole array or just the first 10
1:06
if it's larger than 10.
1:09
Now this is not going to return anything too amazing yet.
1:14
It's given our two players, but they both have score,
1:17
actually our three players, we all have the score
1:19
0, 0, and 0.
1:20
But at least you can kind of see that it's working and then
1:23
what do you think, you can't say the sort's wrong,
1:25
because it is sorting, but as we start playing,
1:27
you'll see the highest winning players
1:29
appearing at the top here, of course.
