Filtering data

Filtering is used to restrict the data you are processing

Filter by an attribute

1. Here is an example filter by a string attribute and equality operator

   for flight in flights
   filter flight.TailNum == 'N592ML'
   return flight

2. Here is an example filter by a integer attribute and > operator

   for flight in flights
   filter flight.Distance > 600
   return flight

3. You can also create compound/composite conditions

   for flight in flights
   filter flight.Distance > 600 
   filter flight.TailNum == 'N592ML'
   return flight

4. The query above is exactly the same as a composite AND

   for flight in flights
   filter flight.Distance > 600 and flight.TailNum == 'N592ML'
   return flight

5. The query above is NOT the same as the as query with OR

   for flight in flights
   filter flight.Distance > 600 or flight.TailNum == 'N592ML'
   return flight
