This is what it asks me to do.
I'm stuck I have asked for help many times each time I still fail even with help makes me think I won't be able to continue in python and makes me unmotivated but I know if I stick with it I will conquer python but it's becoming difficult.
This challenge is a little different. You shouldn't have to write very much code. You probably recognize this code. It's pretty much our shopping_list_2.py from before. I want you to help me with a little refactor, though. Refactoring is when we change the code to make it better, often by creating new functions. Create a new function named main that doesn't take any arguments. Move everything from line 22 (show_help()) and below into your new function. You shouldn't have any code that isn't inside of a function.
def show_help():
# print out instructions on how to use the app
print("What should we pick up at the store?")
print("""
Enter 'DONE' to stop adding items.
Enter 'HELP' for this help.
Enter 'SHOW' to see your current list.
""")
def show_list(shopping_list):
# print out the list
print("Here's your list:")
for item in shopping_list:
print(item)
def add_to_list(shopping_list, new_item):
# add new items to our list
shopping_list.append(new_item)
print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
return shopping_list
def main():
show_help()
# make a list to hold onto our items
shopping_list = []
while True:
# ask for new items
new_item = input("> ")
# be able to quit the app
if new_item == 'DONE':
break
elif new_item == 'HELP':
show_help()
continue
elif new_item == 'SHOW':
show_list(shopping_list)
continue
add_to_list(shopping_list, new_item)
show_list(shopping_list)

def main():
show_help()
# make a list to hold onto our items
shopping_list = []
while True:
# ask for new items
new_item = input("> ")
# be able to quit the app
if new_item == 'DONE':
break
elif new_item == 'HELP':
show_help()
continue
elif new_item == 'SHOW':
show_list(shopping_list)
continue
add_to_list(shopping_list, new_item)
show_list(shopping_list) # this line should be indented too ;-)
