Slip 17 - B) Define a class Date (Day, Month, Year) with functions to accept and display it. Accept date from user. Throw user defined exception “invalid Date Exception” if the date is invalid.

Solution :

class date:
def acceptdate(self):
self.day=int(input("Enter Day: "))
self.month=int(input("Enter Month: "))
self.year=int(input("Enter Year: ")) def printdate(self):
try:
if(self.day>31):
raise Exception("Day value is greater than 31") if(self.month>12):
raise Exception("Month value is greater than 12")

if(self.year<0):
raise Exception("Year value should not be negative")
print("Date: ",self.day,"-",self.month,"-",self.year)
except Exception as e:
print(e) objdate=date()
objdate.acceptdate()
objdate.printdate()

Output:
