Question

Need the following program in Python:

Create a program that calculates the estimated duration of a trip in hours and minutes. This should include an estimated date/time of departure and an estimated date/time of arrival.

Arrival Time Estimator Enter date of departure (YYYY-MM-DD): 2016-11-23 Enter time of departure (HH:MM AM/PM): 10:30 AM Enter miles: 200 Enter miles per hour: 65 Estimated travel time Hours: 3 Minutes: 5 Estimated date of arrival: 2016-11-23 Estimated time of arrival: 01:35 PM Continue? (y/n): y Enter date of departure (YYYY-MM-DD): 2016-11-29 Enter time of departure (HH:MM AM/PM): 11:15 PM Enter miles: 500 Enter miles per hour: 80 Estimated travel time Hours: 6 Minutes: 20 Estimated date of arrival: 2016-11-30 Estimated time of arrival: 05:35 AM Continue? (y/n): n Bye!

Specifications

• For the date/time of departure and arrival, the program should use the YYYY-MM- DD format for dates and the HH:MM AM/PM format for times.
• Create a single data/time string variable based on the two input variables. Use this combined string variable to create a departure date-time object that will be used to determine the estimated arrival date and time.
• For the miles and miles per hour, the program should only accept integer entries like 200 and 65.
• Calculate the hours travelled based on the integer division of miles divided by mph. The minutes are based on the remainder of miles divided by mph. The remainder must then be converted to minutes based on the mph.
• Assume that the user will enter valid data.

Answer 1

Please find the Code as below:

#Importing the datetime classes

import datetime
from datetime import date, time
from datetime import datetime
from datetime import timedelta

print("Arrival Time Estimator")
dep_dt = input("Enter date of departure (YYYY-MM-DD): ")
dep_time = input("Enter time of departure (HH:MM AM/PM): ")

#Combine String to get the Departure Date and Time

departure_date = dep_dt + " " + dep_time

#Use of strptime method to convert the 'departure_date' string into Date object with 12 Hr format

dep_date_obj = datetime.strptime(departure_date, '%Y-%m-%d %I:%M %p')

miles = int(input("Enter miles: "))
miles_ph = int(input("Enter miles per hour: "))
print("Estimated travel time")

#Calculating 'Hours' and 'Minutes' using the 'miles' and 'miles per hour' values

hours = miles//miles_ph
minutes = round(((miles/miles_ph)*60)%60)
print("Hours : ", hours)
print("Minutes : ", minutes)

#Adding the calculated Hours and Minutes with the dep_date_obj using the in-built function timedelta

arr_dt_obj = dep_date_obj + timedelta(hours=hours,minutes=minutes)

#Converting the arr_dt_obj to string using strftime method in 12 Hr format

arrival_date = datetime.strftime(arr_dt_obj, '%Y-%m-%d %I:%M %p')
print("Estimated date of arrival: ", arrival_date[:-8])
print("Estimated time of arrival: ", arrival_date[11:])
