For some destinations, certain time periods, there will be no flights available. We need to add exception handling to our code so that it doesn't break and crash in these situations.
1. Add Bali, DPS, 501 to the last row of the prices sheet in your copy of the Flight Deals Google Sheet:
NOTE: Bali is not a city, but the city in Bali with the largest airport is not well known to most people (Denpasar). To find the historic low price, I used this website: https://www.faredetective.com/farehistory/
2. Run your program and it will crash, we've set the max_stopovers to 0 and there are no direct flights from London to Denpasar (Bali). Use exception handling to prevent this. You'll need to use try/except/else to catch the situations when the flight data is empty and let the code continue without crashing.
HINT: if the flight data is empty, you'll return an empty flight object (None) to main.py you can use continue to let the for loop to continue to run when flight is None. https://www.w3schools.com/python/ref_keyword_continue.asp
