Question

For this assignment, you will write a program to calculate the difference between two datetime values.

Ask the user to enter the first date in the format "YYY/MM/DD HH:MM" or any format you want.
Ask the user to enter the second date in the format "YYY/MM/DD HH:MM" or any format you want.
If the second date is before the first date, just print an error message and quit the program.
Calculate the difference between the two dates.
Print the difference in terms of days and hours.
For example, the difference is 3 days and 2 hours.
Assume the user will enter bad dates.
If the user enters bad data, you should print an elegant message and exit the program.
The bad data can be "2020/04/31#April 31st does not exist Seattle".
You asked for a date, they entered a string.

Answer 1

To calculate the difference between two datetime values in the format "YYY/MM/DD HH:MM", you can parse the input strings into datetime objects and then subtract them using timedelta.

Step-by-step explanation:

To calculate the difference between two datetime values in the format "YYY/MM/DD HH:MM", you can parse the input strings into datetime objects and then subtract them. Here's an example in Python:

from datetime import datetimefirst_date = datetime.strptime(input("Enter the first date: "), "%Y/%m/%d %H:%M")second_date = datetime.strptime(input("Enter the second date: "), "%Y/%m/%d %H:%M")if second_date < first_date: print('Error: Second date is before first date') quit()difference = second_date - first_datedays = difference.dayshours = difference.seconds // 3600print(f'The difference is {days} days and {hours} hours')

This program takes user input for the two dates, checks if the second date is before the first date, and calculates the difference in terms of days and hours using the timedelta object. If the user enters bad dates or invalid data, you can handle it by catching the appropriate exceptions and printing an error message.
