# Task

Your task here is to practice using pivot tables. Depending on the airline and the airport from which the flight started, calculate the number of delays and the minimum and maximum length of the flight. Follow the algorithm:

Create a pivot table:

- Assign the columns
`'Airline'`

and`'AirportFrom'`

to the`index`

argument. - Assign the columns
`'Delay'`

and`'Length'`

to the`values`

argument (in this order). - Using the
`aggfunc`

argument, find the minimum and maximum of the`'Length'`

, and count the number of values in the`'Delay'`

column.

Everything was clear?
