#Python's program to convert number of seconds to days, hours, minutes and seconds.
##

#Define the constants
SECONDS_PER_MINUTE	= 60
SECONDS_PER_HOUR	= 3600
SECONDS_PER_DAY		= 86400

#Read the inputs from user
seconds	= int(input("Enter number of seconds: "))

#Calculate the days, hours, minutes and seconds
days = seconds / SECONDS_PER_DAY
seconds = seconds % SECONDS_PER_DAY

hours = seconds / SECONDS_PER_HOUR
seconds = seconds % SECONDS_PER_HOUR

minutes = seconds / SECONDS_PER_MINUTE
seconds = seconds % SECONDS_PER_MINUTE

#Display the result
print("The duration is: ","%d:%02d:%02d:%02d"%(days,hours,minutes,seconds))
