Challenge 2 - Update Users

We at CashBox would like you to update the user with email address [email protected] to have the last name "Deal".

There is a misspelling of a user whose username is jeffrey. It should only be one f, jefrey.

There are a couple ways to make this change happen, let's see what you can figure out!

After you've completed the TODO's choose Kernel > Restart and Run all Cells to see your results!
