Shop trip

You want to create an application that helps customers to choose the cheapest trip for the products.

There is config.json file that contains:

  • FUEL_PRICE - Price for 1 liter of fuel in dollars.
  • customers - list of dictionaries with information about each customer.
  • shops - list of dictionaries with information about each shop in the city.

You have information about

Customers:

  • name
  • products he wants to buy
  • location
  • money
  • car
    • brand
    • volume of fuel consumption for 100 kilometers.

Shops:

  • name
  • location
  • products that shop provides

Write shop_trip function that doesn't take any argument, where customers calculate how much will cost trip for the products in every shop and pick the cheapest one and ride there if they have enough money. When the customer arrives at the shop his location should equal to shop location. After customer buys products, shop prints purchase receipt using current time. After the shop he arrives home and counts the remaining money.

The cost of the trip consists of three parts: the fuel cost to get to the shop, cost of all products to buy, the fuel cost to get home.

For example, let's say now is 04/01/2021 12:33:41:

 // config.py:

    "FUEL_PRICE": 2.4,

    ],

        {

            }

# main.py:
shop_trip()

# Bob has 55 dollars
# Bob's trip to the Outskirts Shop costs 28.21
# Bob's trip to the Shop '24/7' costs 31.48
# Bob rides to Outskirts Shop
# 
# Date: 04/01/2021 12:33:41
# Thanks, Bob, for your purchase!
# You have bought: 
# 4 milks for 12 dollars
# 2 breads for 2 dollars
# 5 butters for 12.5 dollars
# Total cost is 26.5 dollars
# See you again!
# 
# Bob rides home
# Bob now has 26.79 dollars
#
# Monica has 12 dollars
# Monica's trip to the Outskirts Shop costs 15.65
# Monica's trip to the Shop '24/7' costs 16.84
# Monica doesn't have enough money to make a purchase in any shop

You design application architecture by yourself, but there are some rules:

  • The main.py module must contain only shop_trip function
  • You must create and use at least 2 additional modules
  • Your project use at least 2 classes
Hint: modules structure example if you have problems with architecture. py-shop-trip/
|-- car.py
|-- customer.py
|-- main.py
└-- shop.py

Distance between customer and shop is a distance between their locations in km. Round printed value to two decimal places.

Note: Check your code using this checklist before pushing your solution.
