Shopping_List.py

Question

I would like to spice up this code a little bit by adding a new function named as remove_list() to the existing code. The objective is to ask the user to provide with an input to delete items from the added list.
Below is how I wrote the code and it the DEL operation works but the problem is as the user inputs "DEL" keyword it adds to the existing list which should not be case as "DEL" is supposed to work as a caption to perform the operation.
Can anyone please advise what am I doing wrong:
shopping_list = []
def show_help():
    print("What should we pock up at the store?")
    print("""
Enter 'DONE' to stop adding items.
Enter 'HELP' for this help.
Enter 'SHOW' to see your current list.
""")
def addtolist(item):
    shoppinglist.append(item)
    print("Added! List has items.".format(len(shoppinglist)))
def removelist(item):
    shoppinglist.remove(item)
    print("Deleted! The Item Deleted was. {}".format(item))
def showlist():
    print("Here's your list:")
    count = 1
    for item in shoppinglist:
        print("{}. {}".format(count,item))
        count +=1
showhelp()
while True:
    newitem = input("> ")
if new_item == "DONE":
    break
elif new_item =="HELP":
    show_help()
    continue
elif new_item == "SHOW":
    show_list()
    continue

add_to_list(new_item)

if new_item == 'DEL':
    rem_item = input("Enter the Item you wish to Delete:")
    remove_list(rem_item)
show_list()

Because you have a separate if statement for it, you need to add it as an elif to the other clauses above; at present your code does this:
```python
evaluate these and if one of these three options, do what's needed
if newitem == "DONE":
    break
elif newitem =="HELP":
    showhelp()
    continue
elif newitem == "SHOW":
    show_list()
    continue
YOU ADD WHATEVER IT IS TO THE LIST HERE
addtolist(new_item)
and after you check if it is to be deleted or not
so move this above the segment above!
if newitem == 'DEL':
    remitem = input("Enter the Item you wish to Delete:")
    removelist(remitem)
```
Hope this helps!

Hello Josh,
Thanks for your response.
Below is what I did and it worked for me.
 elif newitem == "DEL":
        remitem = input("Enterthe Item you wish to Delete:")
        removelist(remitem)
        continue
