Question

In this exam, you will design and implement a Python class called 'Date according to the following API specifications. • Do NOT use any existing classes in your answer such as datetime. . You will design your class so that it operates correctly on another planet, where the total days in a year, total days in a month, and months per year may be different. For our planet Earth, you will assume that a year has 360 days and all months have 30 days regardless of what you know. . On planet Earth, there are 12 months in a year. So, you will design accordingly! You will use Time 0 as the reference point to mean the beginning of Time. So, the very first day of history will have the date 01/01/01 Your challenge will be about converting the number of days since the beginning of time (Time 0) into a proper date. For example, according to the assumptions provided above, the fifth day of the third month in year 2018 is 2017 x 360 + 2 x 30+5 = 726185 days since the beginning of time, since 2017 full years and 2 full months have already passed and we are on the fifth day into the third month. For example, 2018 full years (2018 x 360 days) and full six months (6 x 30 days) since the beginning of time, the date is 2019/06/30 , because this date refers to 6 full months after year 2018 ends. That is, 2018 years, 6 months, 0 days after the beginning of time. Similarly, the date 2018 full years (2018 years, 0 months, 0 days) since the beginning of time is 2019/12/30 , because the date is the last day of year 2018. • Hint 1: int( bool( 2018 )), int( bool( 0)), int( bool( 0)) will produce the pattern (1, 0, 0). • *Hint 2. Note that there are a total of 8 cases/patterns possibly with zero year and/or zero month and/or day values. So you need to make sure that you provide the logic for the proper conversion of such cases into dates. With these general specifications in mind, now consider the following before designing and implementing your Date class (a) (10 points] Date( year=1, month=1, day=1 ) will initialize the date object to the provided year, month, and day. This initializer) method should raise an AssertError if the year value is negative and if either the month or day value is not between 1 and the maximum value possible. Remember that you are to design your Date class so that these maximum values can be modified by the users of the class for another planet. (b) [15 points] Provide the ability so that a Date can be printed using print and be displayed at the Python prompt with the format YYYY/MM/DD, where YYYY is a 4-digit year, MM and DD are 2-digit months and days. All three values should be left-padded with zeroes. For example, year 98 should be represented as 8098, and month 5 should be represented as e5 when printed. (C) (15 points) Date.year Date.month and Date.day should be implemented as properties that return the year, month, and day of a given Date

Answer 1

class Date:

def __inti__(self,y,m,d):

self.month=y

self.day=m

self.year=d

def add(time):

self.years+=time//360

self.month+=(time%360)//12

self.day+=(time%360)%12

def sub(time):

self.years+=time//360

self.month+=(time%360)//12

self.day+=(time%360)%12

def __str__(self)

y=str(self.years)

m=str(self.month)

d=str(self.day):

while len(y)<4:

y='0'+y

while len(m)<2:

m='0'+m

while len(d)<2:

d='0'+d

print(y+'/'+m+'/'+d)

if __name__='__main__':

print('enter year month and date')

y=int(input())

m=int(input())

d=int(input())

a=Date(y,m,d)

print(a)

while True:

print('1) add 2)sub 3)exit')

n=int(input())

if n==1:

print('enter time to be added')

a.add(int(input())

print(a)

  

elif n==2:

  print('enter time to be added')

a.add(int(input())

print(a)

elif n==3:

break

else:

print('invalid option')
