Anyone know how to debug this program? Should be a very quick fix. Thanks!

Question

#Make List
ShoppingList = []
print ("Your shopping list is empty.")
nextItem = input("What item do you want to add next: ")

ShoppingList.append(nextItem)

print ("Your shopping list contains: " )
for n in range (0, len(ShoppingList)):
print (n + 1 , ". " , (ShoppingList[n]))

while Option != 3:
print("Do you want to:" + '\n' + " 1. Add an item" + '\n' + " 2. Remove an item" + '\n' + " 3. Quit")
Option = int(input("Enter your choice: "))
while Option > 3 or Option < 1:
Option = int(input("Not a valid choice, enter your choice: "))

if Option == 2:
RemoveItem = input("What item would you like to remove? ")

try:
ShoppingList.remove(RemoveItem)
except ValueError:
print ("ERROR: Item is not on list")
print ("------------------------" + '\n')
print ("Your shopping list contains: " )
for n in range (0, len(ShoppingList)):
print (n + 1 , ". " , (ShoppingList[n]))
print ('\n')

if Option == 1:
nextItem = input("What item do you want to add next: ")
ShoppingList.append(nextItem)
print ("------------------------" + '\n')
print ("Your shopping list contains: " )
for n in range (0, len(ShoppingList)):
print (n + 1 , ". " , (ShoppingList[n]))
print ('\n')

FileObject = open("ShoppingList.txt" , 'w')
for index in range (0, len(ShoppingList)):
FileObject.write (str(ShoppingList[index] + "\n"))

FileObject.close()
print ("Bye!")
