function - Python Date Class Methods -


brand new here!

this first time working python classes , bit confused. wanted try , store dates 3 attributes - year, month, , day (as integers).

what want is:

for ____init____() function take year, month , date (with defaults 1900, 1 , 1) , return month written out:

>>date_one = date( 1973, 5, 2) may 2, 1973 >>date_two = date( 1984) january 1, 1984

for ____str____() function format data string year, month, , day:

>>date_one = date( 1973, 5, 2) >>string = str(date_one) >>string '1973-05-02' >>date_two = date( 1984) >>print date_two 1984-01-01

for same_date_in_year() determine whether 2 dates fall on same date, if aren't in same year

>>date_one = date( 1972, 3, 27) >>date_two = date( 1998, 4, 17) >>date_three = date(1957, 4, 17) >>date_one.same_date_in_year(date_two) false >>date_two.same_date_in_year(date_three) true

what have far:

days_in_month = [0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]  month_names = ['', 'january', 'february', 'march', 'april', 'may', 'june', 'july', 'august', 'september', 'october', 'november', 'december']  class date(object):     year = 1900     month = 1     day = 1      def __init__(self, year=1900, month=1, day=1):         self.year, self.month, self.day = year, month, day         print month_names[month], str(day)+', '+str(year)      def __str__(self, year=1900, month=1, day=1):         self.year, self.month, self.day = year, month, day         print str(year)+'-'+str(month).rjust(2,'0')+'-'+str(day).rjust(2,'0')       def same_date_in_year(year, month, day):      pass   if __name__ == "__main__":     date_one = date( 1972, 3, 27 )     date_two = date( 1998, 4, 13 )     date_three = date( 1996, 4, 13 )     print "date_one " + str(date_one)     print "date_two " + str(date_two)     print "date_three " + str(date_three)     print "date_one.same_day_in_year(date_two)", date_one.same_day_in_year(date_two)     print "date_two.same_day_in_year(date_three)", date_two.same_day_in_year(date_three)     print

i have no idea how class work , functions inside it, before pass. if me, appreciated!

as in comment, you're looking init method, , may able finish rest off on own.

class mdate(object):   """example date class learning purposes. note prefix 'm' in      class name avoid conflicts built-in classes."""   def __init__(self, year=1900, month=1, day=1):     arg in [year, month, day]:       if type(arg) != int:         raise typeexception('year, month, , day must `int`')      self.year = year     self.month = month     self.day = day
