Frame drop_columns

---

drop_columns(self, columns)

Remove columns from the frame.

Parameters:

columns : list

Column name OR list of column names to be removed from the frame.

Returns:

: _Unit

The data from the columns is lost.

Notes

It is not possible to delete all columns from a frame. At least one column needs to remain. If it is necessary to delete all columns, then delete the frame.

Examples

For this example, Frame object my_frame accesses a frame with columns column_a, column_b, column_c and column_d.

>>> print my_frame.schema
[("column_a", str), ("column_b", ta.int32), ("column_c", str), ("column_d", ta.int32)]

Eliminate columns column_b and column_d:

>>> my_frame.drop_columns(["column_b", "column_d"])
>>> print my_frame.schema
[("column_a", str), ("column_c", str)]

Now the frame only has the columns column_a and column_c. For further examples, see: ref:example_frame.drop_columns.
