numpy.array_str

numpy.array_str(a, max_line_width=None, precision=None, suppress_small=None)

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:

a : ndarray

Input array.

max_line_width : int, optional

Inserts newlines if text is longer than max_line_width. The default is, indirectly, 75.

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 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.
