<h3>
what is geo fencing?</h3>
A geofence is a fictitious geographic boundary that can be entered or exited by a mobile device or RFID tag. Geofencing is a location-based service in which an app or other software programme uses radio frequency identification (RFID), Wi-Fi, GPS, or cellular data to trigger a targeted marketing action (such as a text, email, social media advertisement, or app notification).
There are three ways to use this technology to target customers: geotargeting, geofencing, and beaconing. You can track a consumer's location using GPS, Bluetooth, and beacons.

Answer:
Nothing will be printed
Explanation:
You can easily find out that FL is not a member of the Dictionary. And we are checking these in the if. Since the if condition ends up being false, the further process will not run as they will only if the condition ends up being true. Hence, nothing will be printed. 
Remember, del is used to delete a dictionary item. If this would have been a true condition for if then the FL item in the dictionary would have been deleted as it, in that case, would have been present there. And then the next line would have again added the FL item, and print would have printed the dictionary items with FL item as well. However, since if the condition is ending up being false, nothing will be printed. 
If cities['FL'] and print is outside if then 
the output will be 
{'FL': 'Tallahassee', 'GA': 'Atlanta', 'NY': 'Albany', 'CA': 'San Diego'}
