Hello! 😊 It looks like you're making great progress, but there are a couple of critical issues that need to be addressed before we can approve this pull request:
-
Premature Function Termination: In the
shop_tripfunction, thereturnstatement inside the loop causes the function to exit entirely if one customer doesn't have enough money. This prevents subsequent customers from being processed. Consider usingcontinueinstead ofreturnto allow the loop to proceed to the next customer. -
Redundant Attribute Assignment: The
milkattribute in theCustomerclass is being assigned twice. This redundancy can lead to confusion and should be corrected by removing one of the assignments.
Once these issues are resolved, your code will be in great shape! Keep up the good work, and I look forward to seeing the improvements. 🚀

The milk attribute is being assigned twice. This is redundant and could lead to confusion. You should remove one of these assignments.

The return statement inside the else block will terminate the shop_trip function entirely if one customer doesn't have enough money. This means that subsequent customers will not be processed. Consider using continue instead of return to skip to the next customer.

Great job on your submission! 🎉 Your code meets most of the task requirements and constraints, and it's clear you've put in a lot of effort. However, there are a few areas for improvement that could enhance the robustness and clarity of your code:
-
Error Handling: Consider adding error handling for missing keys in dictionaries, such as
shop,customer, andperson_data. This can preventKeyErrorexceptions and make your code more robust. Usingdict.get()with default values or try-except blocks can be helpful. -
Variable Naming: The variable
cheeper_shopappears to be a typo. Renaming it tocheaper_shopwould improve clarity and correctness. -
Logic Validation: Ensure that calculations, such as
customer.money - min_cost, correctly reflect the intended logic, including all necessary costs like products and fuel. -
Data Validation: Validate that
customer.car_consumptionis a valid number and thatcustomer.locationandshop.locationare tuples or lists with at least two elements to avoid runtime errors. -
Consistency: Ensure consistency in JSON key naming between files, such as
"FUEL_PRICE"and"fuel_price".
These improvements will not only help you avoid potential errors but also make your code cleaner and more maintainable. Keep up the great work, and continue to learn and grow from these experiences! 🚀

Consider adding error handling for missing keys in the customer dictionary. Using dict.get() with default values can prevent KeyError exceptions if any expected key is missing.

The variable name cheeper_shop seems to be a typo. Consider renaming it to cheaper_shop for clarity and correctness.

Ensure that cheeper_shop is not empty before calling min(). If it's empty, min() will raise a ValueError. Consider adding a check to handle this case.

The calculation customer.money - min_cost assumes that min_cost includes the cost of products and fuel. Ensure that this logic correctly reflects the intended deduction from the customer's money.

Ensure that customer.location and shop.location are tuples or lists with at least two elements. If not, accessing these indices will raise an IndexError.

Ensure that customer.car_consumption is a valid number. If it's not set or is invalid, this calculation will raise an error.
