pat:str


Regexp pattern. All matching keys will have their description displayed.  
_print_desc:bool, default True


If True (default) the description(s) will be printed to stdout. Otherwise, the description(s) will be returned as a unicode string (for testing).    Returns 
 None by default, the description(s) as a unicode string if _print_desc
is False
   Notes The available options with its descriptions:  compute.use_bottleneck:bool

Use the numba engine option for select operations if it is installed, the default is False Valid values: False,True [default: False] [currently: False]  compute.use_numexpr:bool


Use the numexpr library to accelerate computation if it is installed, the default is True Valid values: False,True [default: True] [currently: True]  display.chop_threshold:float or None


if set to a float value, all float values smaller then the given threshold will be displayed as exactly 0 by repr and friends. [default: None] [currently: None]  display.colheader_justify:‘left’/’right’


Controls the justification of column headers. used by DataFrameFormatter. [default: right] [currently: right]  display.column_space No description available.

[default: 12] [currently: 12]  display.date_dayfirst:boolean

When True, prints and parses dates with the year first, eg 2005/01/20 [default: False] [currently: False]  display.encoding:str/unicode


Defaults to the detected encoding of the console. Specifies the encoding to be used for strings returned by to_string, these are generally strings meant to be displayed on the console. [default: utf-8] [currently: utf-8]  display.expand_frame_repr:boolean


Whether to print out the full DataFrame repr for wide DataFrames across multiple lines, max_columns is still respected, but the output will wrap-around across multiple “pages” if its width exceeds display.width. [default: True] [currently: True]  display.float_format:callable


The callable should accept a floating point number and return a string with the desired format of the number. This is used in some places like SeriesFormatter. See formats.format.EngFormatter for an example. [default: None] [currently: None]  display.html.border:int


A border=value attribute is inserted in the <table> tag for the DataFrame HTML repr. [default: 1] [currently: 1]  display.html.table_schema:boolean


Whether to publish a Table Schema representation for frontends that support it. (default: False) [default: False] [currently: False]  display.html.use_mathjax:boolean

For DataFrames exceeding max_rows/max_cols, the repr (and HTML repr) can show a truncated table (the default from 0.13), or switch to the view from df.info() (the behaviour in earlier versions of pandas). [default: truncate] [currently: truncate]  display.latex.escape:bool


This specifies if the to_latex method of a Dataframe uses escapes special characters. Valid values: False,True [default: True] [currently: True]  display.latex.longtable :bool

This specifies if the to_latex method of a Dataframe uses the longtable format. Valid values: False,True [default: False] [currently: False]  display.latex.multicolumn:bool


This specifies if the to_latex method of a Dataframe uses multicolumns to pretty-print MultiIndex columns. Valid values: False,True [default: True] [currently: True]  display.latex.multicolumn_format:bool


This specifies if the to_latex method of a Dataframe uses multicolumns to pretty-print MultiIndex columns. Valid values: False,True [default: l] [currently: l]  display.latex.multirow:bool

This sets the maximum number of categories pandas should output when printing out a Categorical or a Series of dtype “category”. [default: 8] [currently: 8]  display.max_columns:int


If max_cols is exceeded, switch to truncate view. Depending on large_repr, objects are either centrally truncated or printed as a summary view. ‘None’ value means unlimited. In case python/IPython is running in a terminal and large_repr equals ‘truncate’ this can be set to 0 and pandas will auto-detect the width of the terminal and print a truncated object which fits the screen width. The IPython notebook, IPython qtconsole, or IDLE do not run in a terminal and hence it is not possible to do correct auto-detection. [default: 0] [currently: 0]  display.max_colwidth:int or None


The maximum width in characters of a column in the repr of a pandas data structure. When the column overflows, a “…” placeholder is embedded in the output. A ‘None’ value means unlimited. [default: 50] [currently: 50]  display.max_dir_items:int


The number of items that will be added to dir(…). ‘None’ value means unlimited. Because dir is cached, changing this option will not immediately affect already existing dataframes until a column is deleted or added. This is for instance used to suggest columns from a dataframe to tab completion. [default: 100] [currently: 100]  display.max_info_columns:int


max_info_columns is used in DataFrame.info method to decide if per column information will be printed. [default: 100] [currently: 100]  display.max_info_rows:int or None


df.info() will usually show null-counts for each column. For large frames this can be quite slow. max_info_rows and max_info_cols limit this null check only to frames with smaller dimensions than specified. [default: 1690785] [currently: 1690785]  display.max_rows:int


If max_rows is exceeded, switch to truncate view. Depending on large_repr, objects are either centrally truncated or printed as a summary view. ‘None’ value means unlimited. In case python/IPython is running in a terminal and large_repr equals ‘truncate’ this can be set to 0 and pandas will auto-detect the height of the terminal and print a truncated object which fits the screen height. The IPython notebook, IPython qtconsole, or IDLE do not run in a terminal and hence it is not possible to do correct auto-detection. [default: 60] [currently: 60]  display.max_seq_items:int or None


When pretty-printing a long sequence, no more then max_seq_items will be printed. If items are omitted, they will be denoted by the addition of “…” to the resulting string. If set to None, the number of items to be printed is unlimited. [default: 100] [currently: 100]  display.memory_usage:bool, string or None

“sparsify” MultiIndex display (don’t display repeated elements in outer levels within groups) [default: True] [currently: True]  display.notebook_repr_html:boolean

Controls the number of nested levels to process when pretty-printing [default: 3] [currently: 3]  display.precision:int


Floating point output precision in terms of number of places after the decimal, for regular formatting as well as scientific notation. Similar to precision in numpy.set_printoptions(). [default: 6] [currently: 6]  display.show_dimensions:boolean or ‘truncate’


Whether to print out dimensions at the end of DataFrame repr. If ‘truncate’ is specified, only print out the dimensions if the frame is truncated (e.g. not display all rows and/or columns) [default: truncate] [currently: truncate]  display.unicode.ambiguous_as_wide:boolean


Whether to use the Unicode East Asian Width to calculate the display text width. Enabling this may affect to the performance (default: False) [default: False] [currently: False]  display.unicode.east_asian_width:boolean


Whether to use the Unicode East Asian Width to calculate the display text width. Enabling this may affect to the performance (default: False) [default: False] [currently: False]  display.width:int


Width of the display in characters. In case python/IPython is running in a terminal this can be set to None and pandas will correctly auto-detect the width. Note that the IPython notebook, IPython qtconsole, or IDLE do not run in a terminal and hence it is not possible to correctly detect the width.
