PLEASE READ!!!! I keep asking the same question and the one answering sending the same.
PLEASE USE FILE METHOD!!
PLEASE READ !!!! .txt file
1. Need to save all the inputted data in .txt file (example reservation.txt)
2. compute the total of adults in generate report
3. compute the total of children in generate report
4. compute the total payment in generate report
5. If DELETE RESERVATION is selected, the user needs to input the reservation number to remove the existing reservation.
6. If the GENERATE REPORT is clicked, display the report of all reservations:
reservation = {}
rnum = 0
while True:
adults = {}
Date = {}
Time = {}
name = {}
Children = {}
total = {}
mylist = []
choice = input(
'\nRESTAURANT RESERVATION SYSTEM\nSystem Menu\nA = View all Reservations\nB = Make Reservation\nC = Delete Reservation\nD = Generate Report\nE = Exit\nEnter choice --> ').lower()
f1 = open("reservation.txt", "a")
if choice in 'Aa':
f2 = open("reservation.txt", "r")
print("Records are:")
print(f"#\t\tDate\tTime\t\tName\t\tTotal Adults\t\tTotal children\t\tSubtotal\t\t")
print(f2.read())
f2.close()
elif choice in 'Bb':
try:
rnum += 1
name = input("Enter Name: ")
Date = input("Enter date(DD-MM-YYYY): ")
Time = input("Enter time(HH:MM): ")

print(f1.read())
except ValueError:
print("there is an incorrect value!! try again")
elif choice in 'Cc':
try:
