pandas.get_option

pandas.get_option(pat) = <pandas.core.config.CallableDynamicDoc object at 0xb563fb4c>

Retrieves the value of the specified option.

Available options:

• display.[chop_threshold, colheader_justify, column_space, date_dayfirst, date_yearfirst, encoding, expand_frame_repr, float_format, height, large_repr, line_width, max_categories, max_columns, max_colwidth, max_info_columns, max_info_rows, max_rows, max_seq_items, memory_usage, mpl_style, multi_sparse, notebook_repr_html, pprint_nest_depth, precision, show_dimensions, width]
• io.excel.xls.[writer]
• io.excel.xlsm.[writer]
• io.excel.xlsx.[writer]
• io.hdf.[default_format, dropna_table]
• mode.[chained_assignment, sim_interactive, use_inf_as_null]

Parameters:

pat : str

Regexp which should match a single option. Note: partial matches are supported for convenience, but unless you use the full option name (e.g. x.y.z.option_name), your code may break in future versions if new options with similar names are introduced.

Returns:

result : the value of the option

Raises:

OptionError : if no such option exists

Notes

The available options with its descriptions:

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 day first, eg 20/01/2005 [default: False] [currently: False]

display.date_yearfirst : 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 core.format.EngFormatter for an example. [default: None] [currently: None]

display.height : int

Deprecated. [default: 60] [currently: 15] (Deprecated, use display.max_rows instead.)

display.large_repr : ‘truncate’/’info’

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.line_width : int

Deprecated. [default: 80] [currently: 80] (Deprecated, use display.width instead.)

display.max_categories : int

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: 20] [currently: 20]

display.max_colwidth : int

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. [default: 50] [currently: 50]

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 then 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: 15]

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 or None

This specifies if the memory usage of a DataFrame should be displayed when df.info() is called. [default: True] [currently: True]

display.mpl_style : bool

Setting this to ‘default’ will modify the rcParams used by matplotlib to give plots a more pleasing visual style by default. Setting this to None/False restores the values to their initial value. [default: None] [currently: None]

display.multi_sparse : boolean

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

display.notebook_repr_html : boolean

When True, IPython notebook will use html representation for pandas objects (if it is available). [default: True] [currently: True]

display.pprint_nest_depth : int

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

display.precision : int

Floating point output precision (number of significant digits). This is only a suggestion [default: 7] [currently: 7]

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.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. [default: 80] [currently: 80]

io.excel.xls.writer : string

The default Excel writer engine for ‘xls’ files. Available options: ‘xlwt’ (the default). [default: xlwt] [currently: xlwt]

io.excel.xlsm.writer : string

The default Excel writer engine for ‘xlsm’ files. Available options: ‘openpyxl’ (the default). [default: openpyxl] [currently: openpyxl]

io.excel.xlsx.writer : string

The default Excel writer engine for ‘xlsx’ files. Available options: ‘xlsxwriter’ (the default), ‘openpyxl’. [default: xlsxwriter] [currently: xlsxwriter]

io.hdf.default_format : format

default format writing format, if None, then put will default to ‘fixed’ and append will default to ‘table’ [default: None] [currently: None]

io.hdf.dropna_table : boolean

drop ALL nan rows when appending to a table [default: True] [currently: True]

mode.chained_assignment : string

Raise an exception, warn, or no action if trying to use chained assignment, The default is warn [default: warn] [currently: warn]

mode.sim_interactive : boolean

Whether to simulate interactive mode for purposes of testing [default: False] [currently: False]

mode.use_inf_as_null : boolean

True means treat None, NaN, INF, -INF as null (old way), False means None and NaN are null, but INF, -INF are not null (new way). [default: False] [currently: False]
