Question

Write a class called Time whose only field is a time in seconds. It should have a method called

convert_to_minutes that returns a string of minutes and seconds formatted as in the following

example: if seconds is 230, the method should return '5:50'. It should also have

a method called convert_to_hours that returns a string of hours, minutes, and seconds

formatted analogously to the previous method.

(python)

Answer 1

'''
Python version : 3.6
Python program to create and test class Time
'''

class Time:
  
   # constructor
   def __init__(self, seconds):
       self.seconds = seconds
  
   # function to convert and return a string of minutes and seconds
   def convert_to_minutes(self):
       mins = self.seconds//60 # get the total minutes in the given seconds
       secs = self.seconds - (mins*60) # get the remaining seconds
      
       # return the string of minutes:seconds
       return "%d:%d" %(mins,secs)
  
   # function to convert and return string of hours, minutes, and seconds
   def convert_to_hours(self):
       secs = self.seconds
       hours = secs//3600 # get the total hours in the given seconds
       secs = secs - (hours*3600) # get the remaining seconds
       mins = secs//60 # get the total minutes in the remaining seconds
       secs = secs - (mins*60) # get the remaining seconds
      
       # return the string of hours:minutes:seconds
       return "%d:%d:%d" %(hours,mins,secs)
      
def main():
  
   # test the Time class
   time = Time(230)
   print(time.convert_to_minutes())
   time = Time(4520)
   print(time.convert_to_hours())

#call the main function      
main()      
#end of program
