pandas.DataFrame.to_string

DataFrame.to_string(self, buf=None, columns=None, col_space=None, header=True, index=True, na_rep='NaN', formatters=None, float_format=None, sparsify=None, index_names=True, justify=None, max_rows=None, min_rows=None, max_cols=None, show_dimensions=False, decimal='.', line_width=None)[source]

Render a DataFrame to a console-friendly tabular output.

Parameters:
buf : StringIO-like, optional

Buffer to write to.

columns : sequence, optional, default None

The subset of columns to write. Writes all columns by default.

col_space : int, optional

The minimum width of each column.

header : bool, optional

Write out the column names. If a list of strings is given, it is assumed to be aliases for the column names.

index : bool, optional, default True

Whether to print index (row) labels.

na_rep : str, optional, default ‘NaN’

String representation of NAN to use.

formatters : list 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_format : one-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.

sparsify : bool, optional, default True

Set to False for a DataFrame with a hierarchical index to print every multiindex key at each row.

index_names : bool, optional, default True

Prints the names of the indexes.

justify : str, 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_rows : int, optional

Maximum number of rows to display in the console.

min_rows : int, optional

The number of rows to display in the console in a truncated repr (when number of rows is above max_rows).

max_cols : int, optional

Maximum number of columns to display in the console.

show_dimensions : bool, default False

Display DataFrame dimensions (number of rows by number of columns).

decimal : str, default ‘.’

Character recognized as decimal separator, e.g. ‘,’ in Europe.

New in version 0.18.0.

line_width : int, optional

Width to wrap a line in characters.
Returns:
str (or unicode, depending on data and options)
