648 PointsThe "HELP" option, don't show at the beginning!
If I start my Code, the HELP option, don't show at the beginning. It start immediately with that ">". The HELP option just show up, when I write it. I think, I have the same Code, then Craig.
shopping_list = []
def add_to_list(item):
shopping_list.append(item)
print("Added! List has {} items.".format(len(shopping_list)))
def show_help():
print("What should we pick up at the store?")
print("""
Enter 'DONE' to stop adding items.
Enter 'HELP' for this help.
""")
show_help
while True:
new_item = input("> ")
if new_item == "DONE" :
break
elif new_item == "HELP" :
show_help()
continue
add_to_list(new_item)"""

It works when you ask for it because the second one does have the parentheses.

show_help()
