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("> ")

the loop for the next input:
while True:
new_item = input("> ")
if new_item == "":
continue
# remain input processing code here

should be sufficient. An empty string is false-y.
