var listOfRows = List[Row]() val dfToExtractValues: DataFrame = ??? dfToExtractValues.foreach { x => //Not really important how to generate here the variables //So to simplify all the rows will have the same values var col1 = "firstCol" var col2 = "secondCol" var col3 = "...
it would be nice to add a method for creating a DataFrame from a list of rows represented as general Maps. Right now when I do: val rows : List<Map<String, Any?>> val df = rows.toDataFrame() I get a wired result - DataFrame with columns obtained from the properties of Map class....
I want to create a new polars dataframe from numpy arrays, so I want to add the column-names when creating the dataframe (as I do with pandas). df = pl.DataFrame(noisy_data.tolist(), columns=[f"property_{i}" for i in range(num_columns)]) But polars does not like...
