Remember: The rstrip () or strip () methods can be used to get rid of unwanted newlines on the Inputlines from the Input fles, and "\n" can be appended to a line, when writing to a file, If you want to begin on anew line.Hint: The bead price list can be read Into a two-dimenslonal list to make looking up the price of the beadseasler while processing the order, and also to facilitate the updates of the quantitles. Once the order Isprocessed, the two-dimensional list can be used to write Infomation to the new updated bead list file. Write a Python program to solve the following problem:PURM, 180, 0.59PNKG, 153,0.39Bob the Porcupine wishes to buy some decorative beads for his quills. He heads to the bead shop where theowner, Arnold the Aardvark, Is struggling to write a Python program to compute the cost of a customer's beadorder from some files that have the pertinent Information. Arnold has a comma-separated file contalning theist of beads he has (actually It's a list of codes which represent each Individual type of bead), along with thequantity-on-hand of each type of bead and the corresponding unit price (the price for a single bead of eachtype). Amold also has the customer's bead order In another file and he's wondering how to qulckly print upan Itemized recelpt for the customer and show them the total price.

For each type of bead, If the quantity on hand Is less than 5,then the message "ORDER MORE" should be added to the end of the line In the file.
