Python에서 Do-While 루프를 시뮬레이션하고 반복자를 처리하려면 어떻게 해야 합니까?

while True:
  # Execute loop body
  if break_condition:
    break

# Execute loop body
if not break_condition:
  continue

iterator = list_of_ints.__iter__()
element = None

while True:
  try:
    element = iterator.next()
  except StopIteration:
    break

  print(element)

while True:
  if state == STATE_CODE:
    if "//" in s:
      tokens.add(TOKEN_COMMENT, s.split( "//" )[1])
      state = STATE_COMMENT
    else:
      tokens.add(TOKEN_CODE, s)

  if state == STATE_COMMENT:
    if "//" in s:
      tokens.append(TOKEN_COMMENT, s.split( "//" )[1])
      state = STATE_CODE
    else:
      # Re-evaluate same line
      continue

  try:
    s = i.next()
  except StopIteration:
    break
