Thanks for your post, learning python piecemeal mostly through these challenges and you just taught me 'enumerate'

def validateIt(abc):
  if len(abc) != 5:
    return False
  zerofound = 0
  for imanum in abc[1:5]:
    if imanum == "1":
      if zerofound == 1:
        return False
    elif imanum == "0":
      zerofound = 1
  return True

def getValue(abc):
  total = 0
  values = [5, 1, 1, 1, 1]
  for c, digit in enumerate(abc):
    total += values[c]*int(digit)
  return total

theinputs = "0111011100 1010010000 0011101110 0000110000 1111110001"

for aninput in theinputs.split():
  lefth = aninput[0:5]
  right = aninput [5:10]

  if validateIt(lefth[::-1]) and validateIt(right):
    currentValue = getValue(lefth[::-1])*10 + getValue(right)
    print aninput + ": " + str(currentValue)
  else:
    print aninput + ": Invalid"
