Question

This is my attempt at PS2 #3. I used a lot of internet research though and solved it in a round about way.

Answer 1

lines 9 thru 12 can be accomplished with the range function:
a = range(1,101) - just an observation

don't forget that set() will remove any duplicates - in this case it's ok but for others it may not be desirable

Answer 2

thanks, i was looking for the range function and couldn't remember it. i used set() bc i was having trouble. i was able to iterate the product of 6a+9b+20c and get it into a list but i couldn't not generate a list of the impossible amounts. the set() was a was around that.

Answer 3

all those set methods look like they could be very useful.
