WARNING: This program does not work the way we want it to! It has a logic error and we need to fix it!

RULE: When you open a file in write mode and write to it, you overwrite everything inside the file. If you'd like to add to the end of a file, you can use append mode, specified with an "a".

• Click Run. Notice that when we print our shopping list a second time, we only see "pickles".
• Change the "w" in the open() command to "a", so we don't overwrite our file!
