You don't need to add continue in the loop!

This code works fine without the continue statement in the loop:

shopping_list = []

def print_help():
    print("""
Enter 'DONE' to stop entering items.
Enter 'SHOW' to list items.
Enter 'HELP' to display help.
""")

def print_list(lst):
    for item in lst:
        print(item)

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
    elif new_item == 'SHOW':
        print_list(shopping_list)
    elif new_item == 'HELP':
        print_help()
    else:
        shopping_list.append(new_item)

print("Here's your list:")
print_list(shopping_list)

Continue is the default when we use if/elseif/else in this manner.
