Thank you for your hard work on this project! While your code meets many of the task requirements, there are several critical issues related to error handling that need to be addressed before it can be approved. These issues could lead to runtime errors if the expected data is not present, which impacts the core functionality of your application. Specifically, the code assumes the presence of certain keys in dictionaries and JSON data without checking for their existence, which could result in KeyError exceptions. Adding error handling for these cases will make your code more robust and reliable. Once these changes are made, your solution will be much stronger. Keep up the great work, and I look forward to seeing the improvements! 😊

There was a problem hiding this comment.
The create_car method assumes that the dictionary car_info will always contain the keys 'brand' and 'fuel_consumption'. It would be safer to add error handling to manage cases where these keys might be missing, such as using car_info.get('brand') with a default value or raising an informative exception.

The create_customer method assumes that the dictionary customer_info will always contain the keys 'name', 'product_cart', 'location', 'money', and 'car'. It would be safer to add error handling to manage cases where these keys might be missing, such as using customer_info.get('name') with a default value or raising an informative exception.

The code assumes that the JSON file contains the key 'FUEL_PRICE'. It would be safer to add error handling to manage cases where this key might be missing, such as using data_from_file.get('FUEL_PRICE') with a default value or raising an informative exception.

The code assumes that the JSON file contains a list under the key 'customers'. Consider adding error handling to manage cases where this key might be missing or the data is not in the expected format.

The code assumes that the JSON file contains a list under the key 'shops'. Consider adding error handling to manage cases where this key might be missing or the data is not in the expected format.

The calculation of formate_price could be simplified by using Python's string formatting capabilities, such as f'{price:.2f}' to ensure two decimal places, which would handle both integer and float cases more elegantly.

The create_shop method assumes that the dictionary shop_info will always contain the keys 'name', 'location', and 'products'.

The calculate_total_product_cost method assumes that the customer always wants to buy products available in the shop. Consider adding a check to ensure that the product exists in the customer's product list before attempting to access it, to avoid potential KeyError exceptions.

Great job on implementing the code structure and functionality as per the requirements! 🎉 While the code meets most of the task requirements, there are a few areas that need improvement to enhance robustness and clarity:
-
Error Handling: The error messages for missing keys in the JSON data and other parts of the code are not very informative. Providing more context, such as specifying which key is missing, will make debugging easier.
-
Runtime Errors: In the
calculate_total_product_costmethod, ensure that products in the customer's cart exist in the shop's inventory to avoidKeyError. Similarly, check the lengths ofhome_locationandshop_locationlists in thecalculate_cost_one_waymethod to preventIndexError. -
Type Consistency: Align the type hint for the
moneyproperty in theCustomerclass with the constructor to avoid potential type inconsistencies. -
Logical Conditions: Consider using
<=instead of<when checking if a customer can afford a trip to ensure they can proceed even if their money is exactly equal to the cost.
These improvements will enhance the code's robustness and user-friendliness. Keep up the good work, and make sure to address these issues in future iterations to avoid similar problems. Your effort and dedication to learning are commendable! 🚀

The error handling in the create_car method catches KeyError, but the error message 'not exist' is not very informative. Consider providing more context in the error message, such as which key is missing, to make debugging easier.

There was a problem hiding this comment.
The calculate_cost_one_way method assumes that home_location and shop_location are lists with at least two elements. If these lists are shorter, an IndexError will occur. Consider adding checks to ensure these lists have the expected length before accessing their elements.

Similar to the Car class, the error handling in the create_customer method catches KeyError, but the error message 'not exist' is not very informative. Consider providing more context in the error message, such as which key is missing, to make debugging easier.

The type hint for the money property is int | float, but the constructor only accepts int. Consider aligning the type hint in the constructor with the property to avoid potential type inconsistencies.

The error message 'not exist' for missing keys in the JSON data is not very informative. Consider providing more context in the error message, such as which key is missing, to make debugging easier.

Similar to the previous comment, the error message 'not exist' for missing keys in the JSON data is not very informative. Consider providing more context in the error message, such as which key is missing, to make debugging easier.

Again, the error message 'not exist' for missing keys in the JSON data is not very informative. Consider providing more context in the error message, such as which key is missing, to make debugging easier.

The code assumes that the customer can afford the trip if min_cost_shop[1] < customer.money. However, this does not account for the case where the customer's money is exactly equal to the cost. Consider using <= to ensure the customer can afford the trip even if their money is exactly equal to the cost.

The calculate_total_product_cost method assumes that all products in the customer's cart are available in the shop. If a product is not available, this will raise a KeyError. Consider adding a check to ensure the product exists in the shop's inventory before attempting to access its price.
