Exceptions in Python
- We play dual roles
- Library Creator: We want our functions/methods etc.. to be used effectively. Here we raise exceptions
- Library User: We handle exceptions
- LBYL (Look before you leap): We will check for all the preconditions and try to use in the correct way
- EAFP (Easier to Ask forgiveness than permission)
- Python promotes this approach
- Handle exceptions
- Python official Docs for Errors & Exceptions Refer Here

LT Restaurant feature
- As of now we are able to add or update items, but we are unable to delete them

- Now to implement this feature our dev team wants to store the menu items in a file
- Once we store the menu items ina file, even after restarts we should be able to view menu
- Next Steps:
