- Parameters
- bufstr, Path or StringIO-like, optional, default None
Buffer to write to. If None, the output is returned as a string.
- 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 or sequence, 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, tuple 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/tuple 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

unset.
- max_rowsint, optional
Maximum number of rows to display in the console.
- min_rowsint, optional
The number of rows to display in the console in a truncated repr (when number of rows is above max_rows).
- 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.
- max_colwidthint, optional
Max width to truncate each column in characters. By default, no limit.
New in version 1.0.0.
- encodingstr, default “utf-8”
Set character encoding.
New in version 1.0.
- Returns
- str or None
If buf is None, returns the result as a string. Otherwise returns None.
