I am trying to write a python program to calculate the number of days in a year,by reading through a text file and telling if the date is valid(and if valid,list the number of days in the year),or invalid.I have come up with the folowing code but i am kinda stuck from here on how to calculate the number of days.i will appreciate if someone can look through my codes and help modify or add where necessary.thanks

def isleapYear(year): if year % 400 == 0: return True elif year % 100 == 0: return False elif year % 4 == 0: return True else: return False def validate(m,d,y): if m == 4: d == 30 return True elif m == 6: d == 30 return True elif m == 9: d == 30 return True elif m == 11: d == 30 return True elif m == 2: if isleapYear(year): d == 29 return True else: d == 28 return True else: d == 31 return True def dayNum(m,d,y): dayNum = 31(m - 1) + d if m == 2: dayNum == (4m + 23)/10 return dayNum

i am stuck on how to go about invoking the last two functions in def dayNum(m,d,y),and calculating the number of days.

Thanks peeps

ESPECIALLY since Python is whitespace sensitive, code tags are very important.
