Write a function named weather_delays that returns the airport, year combination that had the most delays due to weather.

Hint: use a tuple (airport, year) as the grouping key.

Write a function named security_delays that returns the year with the most minutes of security-related delays across all airports.

Write a function named greatest_ratio that returns the airport with the highest ratio of total flights to number of carriers.


  • Group by airport to count total flights.
  • Then group by airport to get a list of carriers for each airport; don’t add a carrier to the list if it is already in the list. Split by comma to get individual carrier names.
  • Iterate over the keys (i.e. the airports) to find the airport with the highest ratio (total_flights / number_of_carriers)
