Let's put my little hack back.
0:01
So we know exactly when we're going to win.
0:04
We've got our back and forth with the user already working
0:07
and that's super cool.
0:08
The program is taking the data
0:10
and then it's like having
0:11
basically a conversation with the user.
0:13
That's super cool.
0:14
But what's not cool
0:16
is when I come down here and take a guess
0:17
and then I get it right
0:19
it won't just say, cool, here's a menu, go order.
0:22
It keeps asking us exactly five times.
0:25
So, there's couple of things we can do here.
0:27
One, you look at what's happening so far
0:31
we could take this
0:32
and we could kind of use this
0:34
in like, not the way it's meant to be.
0:37
We could say that's equal to the attempt of limit.
0:43
There, like so.
0:44
Now, by the way
0:45
notice there's a little two spaces I got accidentally here
0:47
and this says there should be a space.
0:49
Maybe there's a bunch of lines
0:51
and I wanted to clean up this code
0:53
PyCharm has this cool thing
0:54
where you can go code, and say, reformat code
0:57
Command + Alt + L, or you can just hit, Command + Alt + L
1:00
and it'll clean up the code.
1:01
So you'll see me reformat code all the time
1:03
to make it nicer.
1:05
Okay so we could do this
1:06
and technically this will work.
1:09
I'll say 10
1:10
oh, not like that.
1:11
I'll say 10 and then I'll say 7
1:13
wooh, you're out.
1:15
But there's just something a little bit ick about this.
1:18
What if down here, we want to say something like
1:21
you're done in however many attempts, right?
1:24
We want to print that out.
1:28
Well, if we come down here and get it
1:29
and you're done in 6.
1:30
No I wasn't, I was done in one!
1:32
So, there's just some kind of weirdness
1:34
like we're kind of abusing what this is for
1:36
and the reason I bring this up
1:38
is Python has a special keyword
1:40
let's say, I don't care what you're doing in the loop
1:42
I don't care what this test is
1:43
just stop.
1:44
Just leave the loop and just go.
1:46
We're done.
1:47
We're done with the loop right now.
1:48
And it's super easy
1:49
you just say, break.
1:50
And then you say, break
1:51
and this just means you come down here
1:53
and then as soon as you get to that
1:54
you just, you don't ever do anything with the loop again
1:57
you just exit out
1:58
and you just pick up right on line 27
1:59
which just says this.
2:01
So let's test that one more time.
2:03
10, no wasn't 10.
2:04
If I take seven, this should do it, and it should exit out.
2:08
Boom. Got it.
2:10
And you're done in some number of attempts.
2:11
It looks like we've got a small ordering issue
2:14
if we're going to print out the number of attempts.
2:16
So let's put that right up there one more time.
2:20
There we go.
2:21
You're done in two attempts.
2:22
Perfect. This is working.
