Nested loop example for the blog - http://nitstorm.github.io/blog/

time.py

hours = int(input("Please enter number of hours: "))
i = 1
total = 0

#Looping through total number of hours
while i<= hours:
	
	# Setting iterator for minutes	
	j = 1
	# Looping through each minute for current hour
	while j <= 60:

		#Setting iterator for seconds
		k = 1
		# Looping through each second for current minute
		while k <=60:
			# Adding 1 to the value of total number of seconds counted
			total = total + 1
			k += 1
		j += 1
	i += 1

print("Total number of seconds in {} hours = {}".format(hours,total))
