Hi. I am not a professional neither but I think a professional does this:
class CurrencyExchange():
def __init__(in_case_callback):
this.callback = in_case_callback
def __run__():
while time.time() - self.rate_timestamp < 5*3600:
... # update exchange rate
if success:
self.rate_timestamp == time.time()
time.sleep(60)
def main():
agio = CurrencyExchange(in_case = callback)
agio.start()
while agio.is_alive():
do_something_delicate(rate_supplied_by=agio)
Notice even if agio is no longer alive, it can still supply exchange rate for
the last delicate_thing, only that it no longer updates punctually. This is
semantic wrong, and I think it is the fault of python: how can something dead
execute its method? In the API, thread.is_alive() should be renamed to
thread.is_activate_and_on_his_own()
