Trip Planner Components Trip Planner consists of planner.py and two custom modules: destinations.py and currency.py

planner.py planner.py is the starting point for this application. It asks the user about their trip,calculates the cost of the trip, and saves that information to a text file named itinerary.txt

destinations.py This module provides information about three travel destinations: Rome, Berlin, andVienna. It defines a function called get_choice() to help the user decide on a destination.

currency.py This module provides two functions: one that converts dollar amounts to euros andanother that converts euro amounts to dollars.

Exception Handling

The application should not crash based on the users input. planner.py should only accept positive (not negative or zero) lengths of stay. The get_choice() function in destinations.py should only accept 1, 2, or 3.
