Hi - I know how to finish the sillycase() function but I have no idea about the quiz - how do I answer that question? I am not sure about the relevancy of that question also from a learning standpoint. is it [number:number:number]?

for x in range(2, 30, 3):
print(x)
2 = start at 2 30 = stop before 30 3 = increment by 3 as we go from 2-30

Kenneth Love
Treehouse Guest TeacherNope. You name where you want to start, then where you want to stop, then how many steps to take each time. Start, stop, step.

1,582 PointsI can only think of [lowerbound:upperbound:stride] as a way of defining what goes into the gaps - in the documentation it has:
proper_slice ::= [lower_bound] ":" [upper_bound] [ ":" [stride] ] lower_bound ::= expression upper_bound ::= expression stride ::= expression
So what goes into the first 2 gaps which both start with "st"?
Kenneth Love
Treehouse Guest TeacherIt's in the last paragraph of the section that I linked you to. Start, stop, and step.

print(name[:]) # prints the string "beven"
print(name[:2]) # from start at index to 2
print(name[::-1]) # reverses the string prints 'neveb'

1,582 PointsHi,
The question mentions that each section begins with "st" - that was my question - no idea what to insert apart from "string" in the blanks!
Kenneth Love
Treehouse Guest TeacherWe talk about it several times in the videos and it's in the documentation for slices, too.
