These options determine the way floating point numbers, arrays and other NumPy objects are displayed. Parameters ---------- precision : int, optional Number of digits of precision for floating point output (default 8). threshold : int, optional Total number of array elements which trigger summarization rather than full repr (default 1000). edgeitems : int, optional Number of array items in summary at beginning and end of each dimension (default 3). linewidth : int, optional The number of characters per line for the purpose of inserting line breaks (default 75). suppress : bool, optional Whether or not suppress printing of small floating point values using scientific notation (default False). nanstr : str, optional String representation of floating point not-a-number (default nan). infstr : str, optional String representation of floating point infinity (default inf). formatter : dict of callables, optional If not None, the keys should indicate the type(s) that the respective formatting function applies to. Callables should return a string. Types that are not specified (by their corresponding keys) are handled by the default formatters. Individual types for which a formatter can be set are:: - 'bool' - 'int' - 'timedelta' : a `numpy.timedelta64` - 'datetime' : a `numpy.datetime64` - 'float' - 'longfloat' : 128-bit floats - 'complexfloat' - 'longcomplexfloat' : composed of two 128-bit floats - 'numpystr' : types `numpy.string_` and `numpy.unicode_` - 'object' : `np.object_` arrays - 'str' : all other strings Other keys that can be used to set a group of types at once are:: - 'all' : sets all types - 'int_kind' : sets 'int' - 'float_kind' : sets 'float' and 'longfloat' - 'complex_kind' : sets 'complexfloat' and 'longcomplexfloat' - 'str_kind' : sets 'str' and 'numpystr' See Also -------- get_printoptions, set_string_function, array2string Notes ----- `formatter` is always reset with a call to `set_printoptions`. Examples -------- Floating point precision can be set: >>> np.set_printoptions(precision=4) >>> print(np.array([1.123456789])) [ 1.1235] Long arrays can be summarised: >>> np.set_printoptions(threshold=5) >>> print(np.arange(10)) [0 1 2 ..., 7 8 9] Small results can be suppressed: >>> eps = np.finfo(float).eps >>> x = np.arange(4.) >>> x**2 - (x + eps)**2 array([ -4.9304e-32, -4.4409e-16, 0.0000e+00, 0.0000e+00]) >>> np.set_printoptions(suppress=True) >>> x**2 - (x + eps)**2 array([-0., -0., 0., 0.]) A custom formatter can be used to display array elements as desired: >>> np.set_printoptions(formatter={'all':lambda x: 'int: '+str(-x)}) >>> x = np.arange(3) >>> x array([int: 0, int: -1, int: -2]) >>> np.set_printoptions() # formatter gets reset >>> x array([0, 1, 2]) To put back the default options, you can use: >>> np.set_printoptions(edgeitems=3,infstr='inf', ... linewidth=75, nanstr='nan', precision=8, ... suppress=False, threshold=1000, formatter=None) N)� _line_width�_summaryThreshold�_summaryEdgeItems�_float_output_precision� _float_output_suppress_small�_nan_str�_inf_str� _formatter)� precision� threshold� edgeitems� linewidth�suppress�nanstr�infstr� formatterr r r r ; s nc C s t ttttttttd�} | S )a Return the current print options. Returns ------- print_opts : dict Dictionary of current print options with keys - precision : int - threshold : int - edgeitems : int - linewidth : int - suppress : bool - nanstr : str - infstr : str - formatter : dict of callables For a full description of these options, see `set_printoptions`.

Parameters ---------- a : ndarray Input array. max_line_width : int, optional The maximum number of columns the string should span. Newline characters splits the string appropriately after array elements. precision : int, optional Floating point precision. Default is the current printing precision (usually 8), which can be altered using `set_printoptions`. suppress_small : bool, optional Represent very small numbers as zero. A number is "very small" if it is smaller than the current printing precision. separator : str, optional Inserted between elements. prefix : str, optional An array is typically printed as:: 'prefix(' + array2string(a) + ')' The length of the prefix string is used to align the output correctly. style : function, optional A function that accepts an ndarray and returns a string. Used only when the shape of `a` is equal to ``()``, i.e. for 0-D arrays. formatter : dict of callables, optional If not None, the keys should indicate the type(s) that the respective formatting function applies to. Callables should return a string. Types that are not specified (by their corresponding keys) are handled by the default formatters. Individual types for which a formatter can be set are:: - 'bool' - 'int' - 'timedelta' : a `numpy.timedelta64` - 'datetime' : a `numpy.datetime64` - 'float' - 'longfloat' : 128-bit floats - 'complexfloat' - 'longcomplexfloat' : composed of two 128-bit floats - 'numpystr' : types `numpy.string_` and `numpy.unicode_` - 'str' : all other strings Other keys that can be used to set a group of types at once are:: - 'all' : sets all types - 'int_kind' : sets 'int' - 'float_kind' : sets 'float' and 'longfloat' - 'complex_kind' : sets 'complexfloat' and 'longcomplexfloat' - 'str_kind' : sets 'str' and 'numpystr' Returns ------- array_str : str String representation of the array. Raises ------ TypeError if a callable in `formatter` does not return a string. See Also -------- array_str, array_repr, set_printoptions, get_printoptions Notes ----- If a formatter is specified for a certain type, the `precision` keyword is ignored for that type. This is a very flexible function; `array_repr` and `array_str` are using `array2string` internally so keywords with the same name should work identically in all three functions. Examples -------- >>> x = np.array([1e-16,1,2,3]) >>> print(np.array2string(x, precision=2, separator=',', ... suppress_small=True)) [ 0., 1., 2., 3.] >>> x = np.arange(3.) >>> np.array2string(x, formatter={'float_kind':lambda x: "%.2f" % x}) '[0.00 1.00 2.00]' >>> x = np.arange(3) >>> np.array2string(x, formatter={'int':lambda x: hex(x)}) '[0x0L 0x1L 0x2L]' Nr )r r z[])r2 )r# r& r' r* rq �itemr rn r rp r� �reducer r� ) r: r~ r+ rV r r� �styler2 r �arrrz r� r r r r � s* b c C s@ t |�� �t |�� � |kr0| |�� d 7 } |}||7 }| |fS )N� )r? �rstrip)�s�line�word� max_line_lenr� r r r � _extendLine s r� c C sv |dkrt d��|r2d| t| �k r2|}|} |} nd}t| �} d} |dk�r"d} |} x4t|�D ](} || | �| }t| | |||�\} } q^W | r�t| | | ||�\} } x:t| dd�D ]*} || | �| }t| | |||�\} } q�W || d �}t| | |||�\} } | | d 7 } d| t|�d � } �nPd} |�� }xlt|�D ]`} | dk�rN| |7 } | t| | ||d |d | |||�7 } | �� |�� d t|d d� } �q8W | �r�| || d 7 } xxt| dd�D ]h} |�s�| | k�r�| |7 } | t| | ||d |d | |||�7 } | �� |�� d t|d d� } �q�W |�s<| dk�rD| |7 } | t| d ||d |d | |||��� d 7 } | S ) zgformatArray is designed for two modes of operation: 1.
