polars.select

polars.select(exprs: Union[str, polars.internals.expr.Expr, Sequence[str], Sequence[polars.internals.expr.Expr], polars.internals.series.Series]) → polars.internals.frame.DataFrame

Run polars expressions without a context.

This is syntactic sugar for running df.select on an empty DataFrame.

DataFrame

Examples

>>> foo = pl.Series("foo", [1, 2, 3])

...         pl.min([foo, bar]),
...     ]
