drop_duplicates(self, unique_columns=None)

Parameters:unique_columns : None (default=None) Returns:: _Unit

Remove duplicate vertex rows, keeping only one vertex row per uniqueness criteria match. Edges that were connected to removed vertices are also automatically dropped.

Examples

Remove any rows that have the same data in column b as a previously checked row:

>>> my_frame.drop_duplicates("b")

The result is a frame with unique values in column b.

Remove any rows that have the same data in columns a and b as a previously checked row:

>>> my_frame.drop_duplicates([ "a", "b"] )

The result is a frame with unique values for the combination of columns a and b.

Remove any rows that have the whole row identical:

>>> my_frame.drop_duplicates()

The result is a frame where something is different in every row from every other row. Each row is unique.
