Because lstrip strips the characters within that set, starting from the
left,
until it encounters a character not in that set. Then it stops. This code
produces the same results, though surely more slowly.

def lstrip(s, set):
  for x in s:
    if x in set:
      return lstrip(s[1:],set)
    return s
