numpy.array_repr#

numpy.array_repr(arr, max_line_width=None, precision=None, suppress_small=None)[source]#

Return the string representation of an array.

Parameters:

arrndarray

Input array.

max_line_widthint, optional

Inserts newlines if text is longer than max_line_width. Defaults to numpy.get_printoptions()['linewidth'].

precisionint, optional

Floating point precision. Defaults to numpy.get_printoptions()['precision'].

suppress_smallbool, optional

Represent numbers very close to zero as zero; default is False. Very close is defined by precision: if the precision is 8, e.g., numbers smaller (in absolute value) than 5e-9 are represented as zero. Defaults to numpy.get_printoptions()['suppress'].

Returns:

stringstr

The string representation of an array.
