Code Check? Am I right?

[r6lay]

Hey everyone so this is my homework assignment and I just wanna make sure my code is right because I'm getting some syntax error 

Write a program (PYTHON) that allows the user to add, delete and organize the items in a list.
Your program will provide the following options:
Append: adds an items, input by the user, at the end of the list.
Delete: removes an item indicated by the user from the list.
Move up: moves an item indicated by the user, to the previous position in the list.
Move Down: moves an item indicated by the user to the next position in the list.
Move Top: moves an item indicated by the user to the the first spot in the list.
Move Bottom: moves an item indicated by the user to the last position in the list.
Swap: swaps two items indicated by the user in the list.
List all: display the items in the list; one item per line.
Quit: allows the user to end the program.
Your program shall show appropriate error messages when trying to move, swap, or delete items not found in the list.
You program shall also properly handle invalid actions, like trying to move up the first item in the list, or trying to move down the last item in the list.
In order to get you started, download the file list_maintainer_base.py which you can find at the bottom of this page.
Here is a sample run. Let's assume we already added the following items (in this order): cake, cookies, ice cream.
Adding "donuts"
List Maintainer 3000
Menu:    [A]dd item to the list,   [R]emove item from list,
        [U] move an item up,      [D] move an item down,
        [T] move item to the top, move item to the bottom.
        [L]ist all items,         [Q]uit program,
        [S]wap two items
Enter an option: A

[Add Item]
Enter item: [b]donuts
...Item added.

Listing all items
List Maintainer 3000
Menu:    [A]dd item to the list,   [R]emove item from list,
        [U] move an item up,      [D] move an item down,
        [T] move item to the top, move item to the bottom.
        [L]ist all items,         [Q]uit program,
        [S]wap two items
Enter an option: L

[List All]
[b]01 cake
02 cookies
03 ice cream
04 donuts


here is the code for the list:
def add_item(alist):
print("[Add Item]")
# Read a string from the user
# Add that string to the end of the list
  
  
def show_menu():
print('''

option = input("Enter an option: ").upper()
while option not in "ARUDTBLSQ":
print("Error: Invalid option. ")

def main():

Please put code in code tags and re-post

[sparkz_alot]

As Larz60+ points out, please post between the code tags as well as the complete error message you are getting between the error tags. Instructions can be found in the Help documents or by pressing the "BBCode Help" button at the bottom of the edit window.  Also, there seems to be "formatting" in your code, to prevent this, when pasting your code between the tags, use " CTRL + SHIFT + V ".

Finally, it's not necessary to post the entire lesson, just the relevant code .

Please put code in code tags and re-post

And remove the formatting so that your post uses the standard forum typography.
