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:
- arrndarray
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']
.
- Returns:
- stringstr
The string representation of an array.
