I’m in the Lots of Math part of Python Functions. It’s the last screen before you complete the lesson.

It is asking me to “return the third number printed mod a.” What exactly is this asking me to do?


I had the same question. Mod is short for modulo, which is the % thing.


I was a bit confused by this question. It says the function should print 3 lines and return 1 value - but in the “should print” part of the comments it shows all the values in one row (not just 1 value).

I did eventually get this right by just returning one value, but then it didn’t look like the suggested solution in the comments - so perhaps the phrasing was a bit odd. Or is it just me?


def lots_of_math(a,b,c,d):
first = a+b
second = c-d
third = first*second
return third % a

This is the code I used… is it correct? Not sure if I was supposed to do that. How do I get it all on one line?


Mod means a lot for some of us, can be modules, modifications, moderations so fix this exercise asap because its confusing.
