database = []

import sys

print()
print("Holiday Packages Database")
print('Packages Loaded:', len(database))
print("+-+-+-+-+-+-+-+-+-+-+-+-+")
print("Available Options")
print("a. Enter a new holiday package")
print("b. Display Inventory (all destinations)")
print('c. Search for a package (view details)')
print('d. Delete a holiday package')
print('e. Show all holiday packages with seasonal discount')

print('Choose an option (a to f) or q to Quit ')

print()
menu = input("Enter a option from list above:")
