Create a range expression.

This can be used in a select, with_column etc.

Be sure that the range size is equal to the DataFrame you are collecting.

Parameters:

low: Lower bound of range.
high: Upper bound of range.
step: Step size of the range.
eager: If eager evaluation is True, a Series is returned instead of an Expr.

Examples

>>> df.lazy().filter(pl.col("foo") < pl.arange(0, 100)).collect()
