Question

I am having a trouble with a python program. I am to create a program that calculates the estimated hours and mintutes. Here is my code.

#!/usr/bin/env python3
#Arrival Date/Time Estimator
#
#

from datetime import datetime
import locale

mph = 0
miles = 0
def get_departure_time():
    while True:
        date_str = input("Estimated time of departure (HH:MM AM/PM): ")
        try:
            depart_time = datetime.strptime(date_str, "%H:%M %p")
        except ValueError:
            print("Invalid date format. Try again.")
            continue
        return depart_time

def get_departure_date():
    while True:
        date_str = input("Estimated date of departure (YYYY-MM-DD): ")
        try:
            depart_date = datetime.strptime(date_str, "%Y-%m-%d")
        except ValueError:
            print("Invalid date format. Try again. ")
            continue
        return depart_date
  
def travel_calculations():

      Estimated_travel_time = (miles / mph)
      a=timedelta(hours=Estimated_travel_time)
      a=str(a)
      a=a.split(':')
      print (" The estimated travel time: ",a[0],'hours and ', a[1],'minutes')

def main():
    print("Arrival Time Estimator\n")
    depart_time = get_departure_time()
    depart_date = get_departure_date()
    travel_calculations()
    miles = input("Enter miles: ")
    mph = input("Enter miles per hour : ")
    return

if __name__ == "__main__":
    main()

Answer 1

Created Functions distance and speed functions to get input from users along with little error handling.

And return distance and speed and store these values to miles, mph

Then pass these variables as parameters to our travel_calculations(miles, mph). In order to calculate total hours and minutes

Python program

from datetime import datetime,timedelta import locale mph = 0 miles = 0 def get_departure_time(): while True: date_str = input("Estimated time of departure (HH:MM AM/PM): ") try: depart_time = datetime.strptime(date_str, "%H:%M %p") except ValueError: print("Invalid date format. Try again.") continue return depart_time def get_departure_date(): while True: date_str = input("Estimated date of departure (YYYY-MM-DD): ") try: depart_date = datetime.strptime(date_str, "%Y-%m-%d") except ValueError: print("Invalid date format. Try again. ") continue return depart_date def distance(): while True: # Get miles User input miles = input("Enter miles to be travelled: ") #validate try: miles = int(miles) # Errorcheck if miles <= 0: print("Enter a Number Greater than 0.\n") else: return miles except ValueError: print("Format Error . Please Try again\n") continue def speed(): while True: # Get speed User input speed = input("Enter miles per hour: ") try: mph = int(speed) # Errorcheck if mph <= 0: print("Enter a Number Greater than 0.\n") else: return mph except ValueError: print("Format Error . Please Try again\n") continue pass    def travel_calculations(miles,mph): # Calculating number of hours and minutes hours = int(miles/mph) minutes = int(((miles/mph)-hours)*60) time_travelled = timedelta(hours=hours, minutes=minutes)    # print our result print("\n\n******Time*******") print("Hours: ", hours) print("Minutes: ", minutes) def main(): print("Arrival Time Estimator\n") depart_time = get_departure_time() depart_date = get_departure_date()    miles = distance() mph = speed() travel_calculations(miles,mph) return if __name__ == "__main__": main()

Output
