polars.DataFrame.with_columns_seq

DataFrame.with_columns_seq(
    *exprs: IntoExpr | Iterable[IntoExpr],
    **named_exprs: IntoExpr,
) → DataFrame

Add columns to this DataFrame.

Added columns will replace existing columns with the same name.

This will run all expression sequentially instead of in parallel. Use this when the work per expression is cheap.

Parameters:

*exprs

Column(s) to add, specified as positional arguments. Accepts expression input. Strings are parsed as column names, other non-expression inputs are parsed as literals.

**named_exprs

Additional columns to add, specified as keyword arguments. The columns will be renamed to the keyword used.

Returns:

DataFrame

A new DataFrame with the columns added.
