Empty shopping list items
When this code is running, if I press "enter" without inputting any text the code still adds an item to the list, so I have an empty or null item. What would be the best way to prevent creating these empty items? This is the part of the code for the new_item input:
while True: new_item = input("> ")

One way to reject empty input would be to check if input is the empty string then
continue the loop for the next input:
while True: new_item = input("> ") if new_item == "": continue # remain input processing code here
