How to create a list with input using commas - Python Shopping List

Hi, my original code is:

shopping_list = list()

print("What would you like to get at the store?")
print("Enter 'DONE' to stop adding new items.")

while True: 
  new_item = input("> ")

  if new_item == 'DONE':
    break

  shopping_list.append(new_item)
  print("Added! List has {} items.".format(len(shopping_list)))
  continue

print("Here are your items:")

for item in shopping_list:
  print(item)

I would like to create this list so that I can input:

Apples, Bananas, Cucumbers...

rather than enter it on a new line each time.

I have tried to figure it out but am unsure.

Part of the issue is how do you get it to stop and how do I get it to still read the number of items?

Other thing I would like to do is instead of it coming up as "> " to enter new items on the first one, how can I get it to start at 1. and somehow add +1 every time there is a new input?

Thanks!

Hi Jake,

You probably want to use .split() and .strip() here. e.g.

shopping_list = list()

print("What would you like to get at the store?")
print("Enter 'DONE' to stop adding new items.")

while True: 
  new_item = input("> ")

  if new_item == 'DONE':
    break
  for item in new_item.split(','):
    shopping_list.append(item.strip())
  print("Added! List has {} items.".format(len(shopping_list)))
  continue

print("Here are your items:")

for item in shopping_list:
  print(item)

.split(',') slits on the comma, and .strip() removes the whitespace.
