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:

arr : ndarray Input array. max_line_width : int, optional The maximum number of columns the string should span. Newlinecharacters 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 usingset_printoptions. suppress_small : bool, optional Represent very small numbers as zero, default is False. Very smallis defined byprecision, if the precision is 8 thennumbers smaller than 5e-9 are represented as zero.

Returns:

string : str The string representation of an array.
