Your read_csv() call to import the CSV data didn't generate an error, but the output is not entirely what we wanted. The row labels were imported as another column without a name. Remember index_col, an argument of read_csv(), that you can use to specify which column in the CSV file should be used quoting optional constant from csv module. Defaults to csv.QUOTE_MINIMAL. If you have set a float_format then floats are converted to strings and thus csv.QUOTE_NONNUMERIC will treat them as non-numeric.. quotechar str, default ‘”’. String of length 1. Character used to quote fields. line_terminator str, optional. The newline character or character sequence to use in the output file. In this exercise, you'll write your predictions to a .csv using the .to_csv() method on a pandas DataFrame. Then you'll evaluate your performance according to the LogLoss metric discussed earlier! You'll need to make sure your submission obeys the correct format. To do this, you'll use your predictions values to create a new DataFrame The to_csv will save a dataframe to a CSV. By default column names are saved as a header, and the index column is saved. If you wish not to save either of those use header=True and/or index=True in the command. For example, in the command below we save the dataframe with headers, but not with the index column. This java tutorial shows how to use the indexOf() method of java.lang.String class. This method returns an int datatype which which corresponds to the index of the string where the method argument str has been found.

Perhaps it would be beneficial to conform the Series.to_csv method to the DataFrame.to_csv method? At least, the following two examples seem relevant (and are the reason I came here): DataFrame.to_csv accepts the keyword parameter path_or_buf. This seems to be completely analogous to the differently named keyword parameter path of Series.to_csv.
