For some reason, the code doesn't want $to$ read the $txt$ files, need help fixing that

Example ManufacturerList.txt$,$ PriceList.txt and ServiceDatesList.txt are provided for reference. Your code will be expected to work with any group input files of the appropriate format. Manufacturers can and will likely be different as will the items.

Interactive Inventory Query Capability

Query the user of an item by asking for manufacturer and item type.

Print a message $($No such item in inventory$)$ if either the manufacturer or the item type is not in the inventory, more that one of either type is submitted or the combination is not in the inventory. Ignore any other words, so $$nice Apple computer$$ is treated the same as $$Apple computer$.$

Print $$Your item is:$$ with the item ID$,$ manufacturer name, item type, and price on one line. Do not provide items that are past their service date or damaged. If there is more than one item, provide the most expensive item.

Also, print $$You may, also, consider:$$ and print information about the same item type from another manufacturer that closes in price to the output item. Only print this if the same item from another manufacturer is in the inventory and is not damaged nor past its service date.

After output for one query, query the user again. Allow $$q$$ to quit.

Using Classes is MANDATORY.

Using Pandas is Prohibited.
