Fill in the Comparator (Solution)

00:00 So the first task we’re at 3 __ 4. Now we have to replace this with a Boolean comparator so that it returns True. I can see that 3 is smaller than 4, so this should return True.

00:17 There you go. Note that if you used a different Boolean comparator, then that can be okay as well, as long as the expression evaluates to True.

00:27 Then let’s try the next one. We have 10 and then 5. And then again, we have to fill something in there to make this True.

00:35 So 10 is bigger than 5, so that should be True. You could also do something like 10 >= 5. That should also be true.

00:47 Or 10 != 5. So there’s a lot of different solutions to all of these exercises, all right? You just want to put in some Boolean comparator that makes this expression be True.

01:01 The next one we have is that "jack"

01:06 and "jill" get compared, and we want to know how we can make this expression True. So I would say for the fun of it, let’s avoid using the != (not equals) comparator, which would also return True.

01:21 But instead, let’s practice using the < (smaller than) or > (bigger than) comparators with strings. So, the first letter of these two strings is the same.

01:30 Then it moves on, comparing the next letter. And here, "a" is smaller than "i", so if I put in here <, "jack" < "jill", then this should return True.

01:41 If you’re surprised why this string comparison works the way you’ve just seen, then revisit the Python Basics course that these review exercises are based on.

01:50 And then we have one more that is 42 and the string "42". We had something similar in the previous exercise. So these two are not equal.

02:01 So we can say 42 as an integer is not equal to the string "42". That should be True as well. Okay, so

02:13 we solved this with the following Boolean comparators: we used 3 < 4 10 > 5, the string "jack" is smaller than the string "jill".

02:23 And again, this is because of the second letter in here. The first one is the same, but the second one in "jack" has a lower index than the one in the right string.

02:31 And then we also compared 42, the integer, to the string "42" and said that these two are not equal to each other. Great, so you’re getting warmed up a little.

02:40 Let’s ramp up the difficulty a little bit.
