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 thanmax_line_width.Defaults tonumpy.get_printoptions()['linewidth'].

precisionint, optional

Floating point precision.Defaults tonumpy.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 aszero.Defaults tonumpy.get_printoptions()['suppress'].
