Have some issues printing my shopping_list. After I type in DONE my list does not want to show up!

Here is my code

shopping_list = []

print("What should we pick up at the store?")
print("Enter 'DONE' to stop adding 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's your list:")

for item in shopping_list:
  print(item)

Thank You

You have a break that's followed by equally-indented lines. Those lines will never be run because they belong to the block that the break is in and the break kicks everything back out to the code after the while loop.

Kenneth Love Your point is right. But, he mentioned he has only issues with printing shopping list. That does mean Issue should be after while termination.

Karthikeyan Palaniswamy His break comes before anything gets added to the list, which would result in a blank list being printed, which would be why the list doesn't show up.

Your program works great. I do not find any mistakes in there. I would recommend you to check indentation properly. In Python Indentation does matter a lot. You may know Python is a indentation language.

Please use the code below. I did intend them well in my text editor. 

shopping_list = []
print("What should we pick up at the store?")
print("Enter 'DONE' to stop adding items")
while True:
  new_item = raw_input("> ")
  if new_item == 'DONE':
    break
  shopping_list.append(new_item)
  print("Added: List has {} items.".format(len(shopping_list)))
  continue
print("Here's your list:")
for item in shopping_list:
  print(item)

I hope It helps
