如何將參數傳遞給datetime.timedelta

Question

我們已經知道datetime.timedelta（hours = 5）是正確的語法。 如何傳遞可以替換下面函數中給出的“小時”的參數？

    def check_time(until_when, def_time, how_long):
            if until_when- datetime.datetime.now() > datetime.timedelta(def_time = how_long):
            input('Task has been finished.\nPress any key to quit\n')
            exit()  

Answer 1

def check_time(until_when, def_time, how_long):
    arg_dict = {def_time:how_long}
    dt = datetime.timedelta(**arg_dict)
    if until_when- datetime.datetime.now() > dt:
        input('Task has been finished.\nPress any key to quit\n')
        exit()
