numpy.array_str#

numpy.array_str(a, max_line_width=None, precision=None, suppress_small=None)[source]#

Return a string representation of the data in an array.

The data in the array is returned as a single string. This function is similar to array_repr, the difference being that array_repr also returns information on the kind of array and its data type.

Parameters:
andarray

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'].
