Answer to Question #198515 in Python for Andu

Question

Project 2: Travel Agency

Implement a program that manages the data of a travel agency. The agency manages the list of hotels that accommodate tourists. For each hotel the agency has the following data: name, address, city, country, number of starts, price per night and a list of facilities. The data are stored into a json file. The application should manage the following characteristics: add a new hotel , remove existing hotel (identified by name) , show hotels of a specific city or country, show hotels that provide a specific facility (e.g., free wifi)

Changes need to be stored back in the file. The above functionalities are implemented through methods of a class named TravelAgency. The application interacts with the user through a menu where the user is asked for the next action to undertake (e.g., 1 -Add new hotel, 2- Remove existing hotel, etc.) Put comments on your code.

Answer 1

import json

with open('hotels.json') as json_file:
    hotels = json.load(json_file)

while True:
    print('(1) Add')
    print('(2) Delete')
    print('(3) Exit')

    i  = int(input())
    
    if i == 1:
        hotels.append({
            "name": input('Name: '),
            "address": input('Address: '),
            "city": input('City: '),
            "country": input('Country: '),
            "number": input('Number: '),
            "price": input('Price per night: ')
        });


    if i == 2:
        j = int(input('Enter idx of item: '))
        if j < len(hotels):
            del hotels[j]
    if i == 3:
        break;


with open('hotels.json', 'w') as outfile:
    json.dump(hotels, outfile)
