numpy.array_repr(arr, max_line_width=None, precision=None, suppress_small=None)ΒΆ

Return the string representation of an array.

Parameters:

arr : ndarray

Input array.

max_line_width : int, optional

The maximum number of columns the string should span. Newline characters split 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, default is False. Very small is defined by precision, if the precision is 8 then numbers smaller than 5e-9 are represented as zero.

Returns:

string : str

The string representation of an array.
