The difference between pass and continue

pass the equivalent of placeholders, it does not have any practical significance

while True:
    pass

Which pass no practical significance, but Python does not recognize blank, so the pass just as the role of the entity while, actually makes no sense

continue is out of this cycle, the next statement is not executed cuntinue, returned directly to the judging section
