Could I split it by every 2nd \"-\" rather than every \"-\" so that it returns two values (\

I think several of the already given solutions are good enough, but just for fun, I did this version:

def twosplit(s,sep):
  first=s.find(sep)
  if first>=0:
    second=s.find(sep,first+1)
      if second>=0:
        return [s[0:second]] + twosplit(s[second+1:],sep)
      else:
        return [s]
    else:
      return [s]
  print twosplit("this-is-a-string","-")
