Booleans for the win!
Time for a showdown! In this exercise, you'll compare looping over a pandas' DataFrame and Boolean indexing head-to-head.
First, loop over the rows of the wildlife_strikes
DataFrame and print the following information about the strike if it involved a Snowy egret, a migratory bird native to North and South America:
- Date of incident (
INCIDENT_DATE
column) - Airport (
AIRPORT
column) - Type of aircraft (
ATYPE
column) - Severity of the damage (
DAMAGE
column)
Then, compare this method with Boolean indexing and print the same information on the subset DataFrame.
