In [37]: 

pd.describe_option() 

display.chop_threshold: [default: None] [currently: None] 
: 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. 
display.colheader_justify: [default: right] [currently: right] 
: 'left'/'right' 
     Controls the justification of column headers. used by DataFrameFormatter. 
display.column_space: [default: 12] [currently: 12]No description available. 

display.date_dayfirst: [default: False] [currently: False] 
: boolean 
     When True, prints and parses dates with the day first, eg 20/01/2005 
display.date_yearfirst: [default: False] [currently: False] 
: boolean 
     When True, prints and parses dates with the year first, eg 2005/01/20 
display.encoding: [default: UTF-8] [currently: UTF-8] 
: 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. 
display.expand_frame_repr: [default: True] [currently: True] 
: 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 it's width exceeds `display.width`. 
display.float_format: [default: None] [currently: <built-in method format of str object at 0x0000000008899AA8>] 
: 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. 
display.height: [default: 60] [currently: 60] 
: int 
     Deprecated. 
    (Deprecated, use `display.height` instead.) 

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

display.max_columns: [default: 20] [currently: 20] 
: int 
     max_rows and max_columns are used in __repr__() methods to decide if 
     to_string() or info() is used to render an object to a string. In case 
     python/IPython is running in a terminal this can be set to 0 and pandas 
     will correctly auto-detect the width the terminal and swap to a smaller 
     format in case all columns would not fit vertically. The IPython notebook, 
     IPython qtconsole, or IDLE do not run in a terminal and hence it is not 
     possible to do correct auto-detection. 
     'None' value means unlimited. 
display.max_colwidth: [default: 50] [currently: 50] 
: 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. 
display.max_info_columns: [default: 100] [currently: 100] 
: int 
     max_info_columns is used in DataFrame.info method to decide if 
     per column information will be printed. 
display.max_info_rows: [default: 1690785] [currently: 1690785] 
: int or None 
     max_info_rows is the maximum number of rows for which a frame will 
     perform a null check on its columns when repr'ing To a console. 
     The default is 1,000,000 rows. So, if a DataFrame has more 
     1,000,000 rows there will be no null check performed on the 
     columns and thus the representation will take much less time to 
     display in an interactive session. A value of None means always 
     perform a null check when repr'ing. 
display.max_rows: [default: 60] [currently: 60] 
: int 
     This sets the maximum number of rows pandas should output when printing 
     out various output. For example, this value determines whether the repr() 
     for a dataframe prints out fully or just a summary repr. 
     'None' value means unlimited. 
display.max_seq_items: [default: None] [currently: None] 
: int or None 

     when pretty-printing a long sequence, no more then `max_seq_items` 
     will be printed. If items are ommitted, 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. 
display.mpl_style: [default: None] [currently: None] 
: 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. 
display.multi_sparse: [default: True] [currently: True] 
: boolean 
     "sparsify" MultiIndex display (don't display repeated 
     elements in outer levels within groups) 
display.notebook_repr_html: [default: True] [currently: False] 
: boolean 
     When True, IPython notebook will use html representation for 
     pandas objects (if it is available). 
display.pprint_nest_depth: [default: 3] [currently: 3] 
: int 
     Controls the number of nested levels to process when pretty-printing 
display.precision: [default: 7] [currently: 7] 
: int 
     Floating point output precision (number of significant digits). This is 
     only a suggestion 
display.width: [default: 80] [currently: 80] 
: 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. 
mode.sim_interactive: [default: False] [currently: False] 
: boolean 
     Whether to simulate interactive mode for purposes of testing 
mode.use_inf_as_null: [default: False] [currently: False] 
: 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).
