cast multiple columns

[djouallah]

is there a simpler way ?

for col_name in df_cols:
			df = df.with_column(col_name, col(col_name).cast(DataType.float64()))

@djouallah you can cast ALL columns via col("*") , but we don't yet have any way to select columns via a pattern or datatype.

cast all columns to string

df.select(daft.col("*").cast(daft.DataType.string()))
