Use one of The character used to denote the start and end of a quoted item. URLs (e.g. per-column NA values. Integers are used in zero-indexed Regex example: '\r\t'. If False, all numeric If True then default datelike columns may be converted (depending on keep_default_dates). Lets load our DataFrame from the example above, only this time only loading the 'Customer' and 'Sales' columns: We can see that by passing in the list of strings representing the columns, we were able to parse those columns only. the default NaN values are used for parsing. If the file contains a header row, those columns will be combined into a MultiIndex. Extra options that make sense for a particular storage connection, e.g. openpyxl supports newer Excel file formats. The string can further be a URL. Using this parameter results in much faster ['AAA', 'BBB', 'DDD'].
