pyspark.pandas.DataFrame.to_string¶
-
DataFrame.
to_string
(buf: Optional[IO[str]] = None, columns: Optional[Sequence[Union[Any, Tuple[Any, …]]]] = None, col_space: Union[str, int, Dict[Union[Any, Tuple[Any, …]], Union[str, int]], None] = None, header: bool = True, index: bool = True, na_rep: str = 'NaN', formatters: Union[List[Callable[[Any], str]], Dict[Union[Any, Tuple[Any, …]], Callable[[Any], str]], None] = None, float_format: Optional[Callable[[float], str]] = None, sparsify: Optional[bool] = None, index_names: bool = True, justify: Optional[str] = None, max_rows: Optional[int] = None, max_cols: Optional[int] = None, show_dimensions: bool = False, decimal: str = '.', line_width: Optional[int] = None) → Optional[str]¶ Render a DataFrame to a console-friendly tabular output.
Note
This method should only be used if the resulting pandas object is expected to be small, as all the data is loaded into the driver’s memory. If the input is large, set max_rows parameter.
- Parameters
- bufStringIO-like, optional
Buffer to write to.
- columnssequence, optional, default None
The subset of columns to write. Writes all columns by default.
- col_spaceint, optional
The minimum width of each column.
- headerbool, optional
Write out the column names. If a list of strings is given, it is assumed to be aliases for the column names
- indexbool, optional, default True
Whether to print index (row) labels.
- na_repstr, optional, default ‘NaN’
String representation of NAN to use.
- formatterslist or dict of one-param. functions, optional
Formatter functions to apply to columns’ elements by position or name. The result of each function must be a unicode string. List must be of length equal to the number of columns.
- float_formatone-parameter function, optional, default None
Formatter function to apply to columns’ elements if they are floats. The result of this function must be a unicode string.
- sparsifybool, optional, default True
Set to False for a DataFrame with a hierarchical index to print every multiindex key at each row.
- index_namesbool, optional, default True
Prints the names of the indexes.
- justifystr, default None
How to justify the column labels. If None uses the option from the print configuration (controlled by set_option), ‘right’ out of the box. Valid values are
left
right
center
justify
justify-all
start
end
inherit
match-parent
initial
unset.
- max_rowsint, optional
Maximum number of rows to display in the console.
- max_colsint, optional
Maximum number of columns to display in the console.
- show_dimensionsbool, default False
Display DataFrame dimensions (number of rows by number of columns).
- decimalstr, default ‘.’
Character recognized as decimal separator, e.g. ‘,’ in Europe.
- line_widthint, optional
Width to wrap a line in characters.
- Returns
- str (or unicode, depending on data and options)
String representation of the dataframe.

>>> print(df.to_string(max_rows=2)) col1 col2 0 1 4 1 2 5
