polars.DataFrame.select_seq#

DataFrame.select_seq(

*exprs: IntoExpr | Iterable[IntoExpr],

**named_exprs: IntoExpr,

) → DataFrame[source]#

Select columns from this LazyFrame.

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

Parameters:

*exprs: Column(s) to select, 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 select, specified as keyword arguments. The columns will be renamed to the keyword used.
