sort(self, columns, ascending=True)

[BETA] Sort the data in a frame.

Parameters:

columns : str | list of str | list of tuples

Examples

Consider the frame

>>> frame.inspect()
[#]  col1  col2
==================
[0]     3  foxtrot
[1]     1  charlie
[2]     3  bravo
[3]     2  echo
[4]     4  delta
[5]     3  alpha

Sort a single column:

>>> frame.sort('col1')
[===Job Progress===]
>>> frame.inspect()
[#]  col1  col2
==================
[0]     1  charlie
[1]     2  echo
[2]     3  foxtrot
[3]     3  bravo
[4]     3  alpha
[5]     4  delta

Sort a single column descending:

>>> frame.sort('col2', False)
[===Job Progress===]
>>> frame.inspect()
[#]  col1  col2
==================
[0]     3  foxtrot
[1]     2  echo
[2]     4  delta
[3]     1  charlie
[4]     3  bravo
[5]     3  alpha

Sort multiple columns:

>>> frame.sort(['col1', 'col2'])
[===Job Progress===]
>>> frame.inspect()
[#]  col1  col2
==================
[0]     1  charlie
[1]     2  echo
[2]     3  alpha
[3]     3  bravo
[4]     3  foxtrot
[5]     4  delta

Sort multiple columns descending:

>>> frame.sort(['col1', 'col2'], False)
[===Job Progress===]
>>> frame.inspect()
[#]  col1  col2
==================
[0]     4  delta
[1]     3  foxtrot
[2]     3  bravo
[3]     3  alpha
[4]     2  echo
[5]     1  charlie

Sort multiple columns: ‘col1’ decending and ‘col2’ ascending:

>>> frame.sort([ ('col1', False), ('col2', True) ])
[===Job Progress===]
>>> frame.inspect()
[#]  col1  col2
==================
[0]     4  delta
[1]     3  alpha
[2]     3  bravo
[3]     3  foxtrot
[4]     2  echo
[5]     1  charlie
