Define the Python class called Date as outlined below: 1. The init method for Date takes the first formal parameter self, and takes three Integers d, m, and y as input in that order, and stores each of them as instance variables (d is the day, m is the month, and y is the year). You may choose to have additional instance variables if it is found to be useful to you. 2. The class contains accessors for d, m, and y. The names of the accessors are getDay(self), getMonth(self), and getYear(self), respectively. 3. The class contains a method named Next(self) that takes only the formal parameter self. The method returns a Date object that is one day later than the current object. (for example, If the date was 31/12/2019 the next date should be 1/1/2020) 4. The class contains a method named Prev(self) that takes only the formal parameter self. The method returns a Date object that is one day earler than the current object. I 5. The class contains a method named isBefore(self, d) that takes in the formal parameter self and a Date object d. The method returns the Boolean True if the current date is before d and the Boolean False otherwise. 6. The class contains a method named isAfter(self, d) that takes in the formal parameter self and a Date object d. The method returns the Boolean True if the current date is after d and the Boolean False otherwise. 7. The class contains a method named isEqual(self, d) that takes in the formal parameter self and a Date object d. The method returns the Boolean True if the current date is the same as d and the Boolean False otherwise. 8. The class contains a method named add_days(self, n) that takes in the formal parameter self and an integer n. The method returns a Date object that is n days later than the date of the current object. (for example, If the date is 23/12/1998 and I add 15 days, the new date should be 7/1/1999) 9. The class contains a method named days between(self, d) that takes in the formal parameter self and a Date object d. The method returns an integer that is the number of days between the current date and d. (for example, the number of days between 19/03/2020 and 12/03/2020 Is 7 days and the number of days between 12/03/2020 and 19/03/2020 is also 7 days) Note: Make sure the spelling of the methods is the exact same as outlined in the requirements. Hint: Think about all of the possible scenarlos for which these methods must work (we may have done something in Tutorial ("cough*7*cough") that might help you outl).

Define the Python class called Date as outlined below:
1. The init method for Date takes the first formal parameter self, and takes three Integers d,
m, and y as input in that order, and stores each of them as instance variables (d is the day, m is
the month, and y is the year). You may choose to have additional instance variables if it is found
to be useful to you.
2. The class contains accessors for d, m, and y. The names of the accessors are getDay(self),
getMonth(self), and getYear(self), respectively.
3. The class contains a method named Next(self) that takes only the formal parameter self. The
method returns a Date object that is one day later than the current object. (for example, If the
date was 31/12/2019 the next date should be 1/1/2020)
4. The class contains a method named Prev(self) that takes only the formal parameter self. The
method returns a Date object that is one day earler than the current object.

5. The class contains a method named isBefore(self, d) that takes in the formal parameter self and
a Date object d. The method returns the Boolean True if the current date is before d and the
Boolean False otherwise.
6. The class contains a method named isAfter(self, d) that takes in the formal parameter self and a
Date object d. The method returns the Boolean True if the current date is after d and the Boolean
False otherwise.
7. The class contains a method named isEqual(self, d) that takes in the formal parameter self and a
Date object d. The method returns the Boolean True if the current date is the same as d and the
Boolean False otherwise.
8. The class contains a method named add_days(self, n) that takes in the formal parameter self and
an integer n. The method returns a Date object that is n days later than the date of the current
object. (for example, If the date is 23/12/1998 and I add 15 days, the new date should be
7/1/1999)
9. The class contains a method named days between(self, d) that takes in the formal parameter self
and a Date object d. The method returns an integer that is the number of days between the
current date and d. (for example, the number of days between 19/03/2020 and 12/03/2020 Is 7
days and the number of days between 12/03/2020 and 19/03/2020 is also 7 days)
Note: Make sure the spelling of the methods is the exact same as outlined in the requirements.
Hint: Think about all of the possible scenarlos for which these methods must work (we may have done
