How To Test

1. Run the Python Connect SDK example
2. When you see Would you like to delete the newly created item from your vault? (y/n), enter n

Current Behavior

Your answer should be either 'y' or 'n'. Would you like to delete the newly created item from your vault? (y/n) is continuously prompted, until y is entered.

New (Fixed) Behavior

The item is not deleted from the vault and the example script terminates. Both uppercase Y/N and lowercase y/n are accepted.
