EdgeFrame drop_rows

---

drop_rows(self, predicate)

Erase any row in the current frame which qualifies.

Parameters:

predicate : function

UDF which evaluates a row to a boolean; rows that answer True are dropped from the Frame

Examples

For this example, my_frame is a Frame object accessing a frame with lots of data for the attributes of lions, tigers, and ligers. Get rid of the lions and tigers:

>>> my_frame.drop_rows(lambda row: row.animal_type == "lion" or
...    row.animal_type == "tiger")

Now the frame only has information about ligers.
