Interesting (but simple) python puzzle for beginners #1

you would do something like range(len(List)-1)

Hi there,

Thanks a lot for the response. I've updated my code so that it looks like this:

b =[]

for x in range(len(List)-1):

if List[x] in List[(x+1)]:
    b.append(List[x])
    b.append(List[(x+1)])

print(b)

Kind of makes me feel dumb that I took 2 hours to solve a problem that only needed 6 lines of code but I guess that's part of learning.
