HELP function not working

When I run this code, the HELP function doesn't seem to work

shopping_list=[]

def show_help():

print out instructions on how to use the app

print("what should I do today?")
print("""

Enter 'DONE' to stop adding items. Enter 'HELP' for this help Enter 'SHOW' to see the current list """)

show_help()

while True: #ask for new item new_item= input("> ") if new_item == 'DONE': break elif new_item== 'HElP': show_help() continue #be able to quit the app

add new items to our list

shopping_list.append(new_item)

print out the list

print("here's your list:")

for item in shopping_list: print(item)

Hi Laknath,

I see a typo inside this line:

elif new_item== 'HElP'
# change it to HELP :)

I have refactored your code a little:

shopping_list = []

# print out instructions on how to use the app
def show_help():
    print("what should I do today?")
    print("""
Enter 'DONE' to stop adding items.
Enter 'HELP' for this help Enter 'SHOW' to see the current list
""")

show_help()

while True:
# ask for new item
    new_item = input("> ")
    if new_item == 'DONE':
        break
# show_help() continue #be able to quit the app
    elif new_item == 'HELP':
        show_help()
# add new items to our list
    shopping_list.append(new_item)

# show list
print("here's your list:")

for item in shopping_list:
    print(item)

I hope I could help.

awesome, thank you. I figured that I had typed "HElP" instead of "HELP"
