DataFrame - sort_values() function

The sort_values() function is used to sort by the values along either axis.

Syntax:

DataFrame.sort_values(self, by, axis=0, ascending=True, inplace=False, kind='quicksort', na_position='last')

Parameters:

Name	Description	Type/Default Value	Required / Optional
by	Name or list of names to sort by. if axis is 0 or ‘index’ then by may contain index levels and/or column labels if axis is 1 or ‘columns’ then by may contain column levels and/or index labels Changed in version 0.23.0: Allow specifying index or column level names.	str or list of str	Required
axis	Axis to be sorted.	{0 or ‘index’, 1 or ‘columns’} Default Value: 0	Required
ascending	Sort ascending vs. descending. Specify list for multiple sort orders. If this is a list of bools, must match the length of the by.	bool or list of bool Default Value: True	Required
inplace	If True, perform operation in-place.	bool Default Value: False	Required
kind	Choice of sorting algorithm. See also ndarray.np.sort for more information. mergesort is the only stable algorithm. For DataFrames, this option is only applied when sorting on a single column or label.	{‘quicksort’, ‘mergesort’, ‘heapsort’} Default Value: ‘quicksort’	Required
na_position	Puts NaNs at the beginning if first; last puts NaNs at the end.	{‘first’, ‘last’} Default Value: ‘last’	Required

Returns: sorted_obj - DataFrame or None DataFrame with sorted values if inplace=False, None otherwise.
