Thank you for your hard work on this project! While your code meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:
-
Customer's Financial State: The
ride_homemethod in theCustomerclass does not update themoneyattribute after spending money. This is crucial for maintaining an accurate financial state for the customer. -
Product Handling in
ShopClass: Theprint_checkmethod assumes certain products are always present, which can lead to errors if they are not. Additionally, theself.products.get(product)expression may returnNone, causing aTypeError. Please ensure these cases are handled properly. -
Efficiency and Error Handling: In the
shop_tripfunction, consider storing the result ofmin(trip_cost_dict)in a variable to avoid recalculating it. Also, ensure there's a check for an emptytrip_cost_dictto prevent aValueError.
Addressing these issues will significantly improve the functionality and robustness of your code. Keep up the great work, and I'm confident you'll nail it with these adjustments! 😊

In the ride_home method, the money attribute is not updated after spending money. You should update self.money by subtracting spend_money from it to reflect the current financial state of the customer.

The condition if customer.money < min(trip_cost_dict): assumes that trip_cost_dict is not empty. Ensure that there is a check to handle the case where trip_cost_dict might be empty, which could lead to a ValueError when calling min().

The logic for selecting the shop with the minimum cost is correct, but it would be more efficient to store the result of min(trip_cost_dict) in a variable and reuse it in line 55 to avoid recalculating it.

Ensure that the ride_home method updates the customer's money correctly, as previously noted in the Customer class review. This will ensure that the customer's financial state is accurately reflected after the trip.

The expression self.products.get(product) may return None if the product is not found in the shop's inventory. This could lead to a TypeError when multiplying None by qty. Consider providing a default value (e.g., 0) to avoid this issue.

The print_check method assumes that 'milk', 'bread', and 'butter' are always present in the customer's cart. If any of these products are not in the cart, None will be returned, leading to potential errors. Consider checking if the product exists in the cart before attempting to access its quantity and price.
