Eleven has been living in Hawkins Lab for as long as she can remember. Her powers are incredible — but to track them, Hopper needs your help storing information about her abilities.
Your mission
Create three variables: `name` (her name, a string), `power_level` (an integer, set it to 11), and `can_fly` (a boolean — for now it's False). Then print all three.
