[Tutor] Please help to debug this function.. it takes a date and num. of days and returns startdate and enddate
Hi Folks, I have written a function that takes a date and an integer representing the number of days. Please test it, comment onthe logic. Here is the code: CODE BEGINS The function takes two arguments, date and number of days. It checks for the right format and if the format is okay, it calculates the end date. import stringimport datetimeimport traceback def dateCheck(date1,num_days): flag = True startdate = None enddate = None if num_days 0 or num_days 31: flag = False print The argument for -n has to be between 0 and 31 return (flag,startdate,enddate) else: date_lst = string.split(date1,/) ln = len(date_lst) if ln != 3 : flag = False print The argument for -D option has to be in the format: dd/mm/ return (flag,startdate,enddate) else: date_lst.reverse() print date_lst try: if int(date_lst[0]) 2000: flag = False print The year cannot be earlier than 2000 and it should be in the format ''. return (flag,startdate,enddate) except ValueError: flag = False err_msg = traceback.format_exc() index = string.find(err_msg,'Value') print err_msg[index:] return (flag,startdate,enddate) try: startdate = datetime.date(int(date_lst[0]),int(date_lst[1]),int(date_lst[2])) enddate = startdate + datetime.timedelta(days=num_days) print startdate, enddate except ValueError: flag = False startdate = None enddate = None err_msg = traceback.format_exc() index = string.find(err_msg,'Value') print err_msg[index:] return (flag,startdate,enddate) if enddate datetime.date.today(): enddate = datetime.date.today() if startdate datetime.date.today(): flag = False startdate = None enddate = None print The -D option should have a date not later than today's date return (flag,startdate,enddate) CODE ENDS TIA.

Hi Asrarahmed, You should be able to write your own tests too. You might want to look at: http://www.diveintopython.org/unit_testing/index.html for an example of how to write unit tests; the author there goes through an example with a Roman Numeral program written with unit tests. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
