Question

use Python and please comments every step.

[25] 6. Write a program that reads from standard input, two times in military format and prints the number of hours and minutes between the two times. Assume that the second time is always ahead of the first time. You should avoid using conditional statement (if-else) for this program. Your program must query the user for the two times and output the difference based on the two sample runs given below. Please enter the first time: 0900 Please enter the second time: 1730 Difference between the two times: 8 hours and 30 minutes. Please enter the first time: 1730 Please enter the second time: 0900 Difference between the two times: 15 hours and 30 minutes.

CodeToCopy:

timediff.py

#python 2.7

# taking time1 from user

time1 = raw_input("Please enter the first time: ")

# taking time2 from user

time2 = raw_input("Please enter the second time: ")

# convertin them as integers

time1 = int(time1)

time2 = int(time2)

# fetching minutes from the time1

mins1 = time1 % 100

# fetching minutes from the time2

mins2 = time2 % 100

# fetching hours from the time1

hours1 = time1/100

# fetching hours from the time2

hours2 = time2/100

# calculating hour difference between time2 and time1

diff_hours = (hours2 - hours1) % 24

# minute difference between time2 and time1

diff_mins = (mins2 - mins1);

# if minute difference is less than 0, hours need to be reduced by 1 to

# get actual hour difference

diff_hours = (diff_hours, diff_hours-1) [ diff_mins < 0]

# finalizing the range of minute difference time2 and time1

diff_mins = diff_mins % 60

# printing difference between two times

print("Difference between the two times: " + str(diff_hours) + " hours and " + str(diff_mins) + " minutes.")

timediff.py

#python 3.x

# taking time2 from user

time2 = input("Please enter the second time: ")

# convertin them as integers

time1 = int(time1)

time2 = int(time2)

# fetching minutes from the time1

# fetching minutes from the time2

# fetching hours from the time1

hours1 = time1/100

# fetching hours from the time2

hours2 = time2/100

# calculating hour difference between time2 and time1

# minute difference between time2 and time1

# get actual hour difference

# printing difference between two times

print("Difference between the two times: " + str(diff_hours) + " hours and " + str(diff_mins) + " minutes.")
