So, in this question,
we ask what's printed by the following statements.
So, mydict is a dictionary with four key value pairs,
and we print out mydict.get cat,
divided by mydict.get dog.
Here, we're using division without a remainder which just gives us an integer.
Mydict.get cat is 12,
and mydict.get dog is six,
and so the value of 12 over six is going to be two.
So, in this question,
we're asked what's printed by the following statement?
So, we create that same dictionary, and now,
we print out the value dog in mydict,
so that asks, is dog a key in my dictionary?
We can see that it is.
It has the value six,
but all we care about is that it is a key.
Here, we create that same dictionary and we print out the value 23 in mydict.
Here, we have a key elephant that has the value 23,
but remember that in only asks,
is 23 a key in my dictionary?
In this case, it's not.
Our only keys are cat,
dog, elephant, and bear.
It doesn't matter that it just so happens to be a value.
The value here of this overall expression is going to be false.
So, here, we first assign total to be
zero and then we create the same dictionary that we had before,
and we loop through all of the keys in our dictionary.
So, A key is going to be cat,
dog, elephant, and bear,
not necessarily in that order, and we say,
if the length of that key,
so every one of these keys is a string.
So, if that string is longer than three characters,
then add its value to total.
So, the first thing I would ask are what are
the keys that are longer than three characters?
That's just going to be elephant and bear.
So, for cat and dog,
this statement is not going to run because
the key cat is not longer than three characters and same thing for the key dog.
So, for elephant and bear,
then we're going to say total equals total plus my dictionary plus that value.
So, we're going to first assign total to be zero plus,
let's suppose that elephant comes before bear,
so zero plus mydict sub elephant,
so zero plus 23,
so total gets the value 23.
Then, by the time we get to the key bear,
then we're going to say total equals its old value,
so 23 plus the value associated with the key bear which is 20,
so 23 plus 20,
which is going to leave total at 43.
So, the answer here is going to be B.
That's all for now. Until next time.
