pyspark.pandas.Index.to_list

Index.to_list()

Return a list of the values.

These are each a scalar type, which is a Python scalar (for str, int, float) or a pandas scalar (for Timestamp/Timedelta/Interval/Period)

Note

This method should only be used if the resulting list is expected to be small, as all the data is loaded into the driver’s memory.

Examples

Index

>>> idx = ps.Index([1, 2, 3, 4, 5])
>>> idx.to_list()
[1, 2, 3, 4, 5]

MultiIndex

>>> tuples = [(1, 'red'), (1, 'blue'), (2, 'red'), (2, 'green')]
>>> midx = ps.MultiIndex.from_tuples(tuples)
>>> midx.to_list()
[(1, 'red'), (1, 'blue'), (2, 'red'), (2, 'green')]
