One of the first interesting parts
0:01
of programming that we focused on
0:03
was conditional statements.
0:05
Remember we were talking about how to make code, decide
0:08
and make it interactive?
0:10
So, here we're getting a random number from the computer.
0:12
Remember that was the number of M&Ms in the jar
0:15
and then we're getting a guess from the user
0:17
on whether or not, you know, whatever number of M&Ms
0:19
they thought there were there.
0:21
And then we can check.
0:22
If the guess is too low, we can say
0:24
Your guess is too low.
0:25
If it's too high, we say, it's too high
0:27
and if they win, then they win.
0:28
And this let us go around and around
0:30
until they got the number of guesses right
0:32
or they ran out of attempts.
0:34
Remember they got five attempts to get it right
0:36
they got a free lunch, or they just didn't get anything
0:39
and had to pay for lunch.
0:40
So, these conditional statements either are if
0:42
elif, there's all these combinations you can have
0:45
but they always start with if
0:46
and they have some kind of truthy test
0:48
like guess less the number
0:50
or if you have a string
0:51
you just put the string there and say
0:52
if there is a value for the string
0:54
we're going to do this thing and so on.
0:56
So, if, elif, else
0:58
and you put the -uthy type of statements in there
1:00
to check them.
