If no arguments are passed, this function is syntactic sugar for `col("*")`. Otherwise, this function is syntactic sugar for `col(names).all()`. Parameters ---------- *names Name(s) of the columns to use in the aggregation. ignore_nulls * If set to `True` (default), null values are ignored. If there are no non-null values, the output is `True`. * If set to `False`, `Kleene logic`_ is used to deal with nulls: if the column contains any null values and no `False` values, the output is null. .. _Kleene logic: https://en.wikipedia.org/wiki/Three-valued_logic See Also -------- all_horizontal Examples -------- Selecting all columns. >>> df = pl.DataFrame( ... { ...
