I am trying to verify ZIP Codes inputted into my text file and then asked the user to input a ZIP Code. Then tell them if it's a valid ZIP Code or not based on what's in my text file. I have created a loop to ask them to enter another one if they want to and have created a way to exit the code. If the zip code is valid, it needs to display the barcode and then ask if the user wants to enter another. I don't understand why this code is not working. Everything is working Except for the barcode output. for example, "12345 barcode => ::||::|:|::||::|::|:|:|:" and I'm only getting || for the output. Can someone please help with this last part of the code?
