savez(file, *args, **kwds)	Saves one or more arrays into a file in uncompressed .npz format.
savez_compressed(file, *args, **kwds)	Saves one or more arrays into a file in compressed .npz format.

String formatting

array_repr(arr[, max_line_width, precision, …])	Returns the string representation of an array.
array_str(arr[, max_line_width, precision, …])	Returns the string representation of the content of an array.
