numpy.printoptions

numpy.printoptions(*args, **kwds)[源代码]

Context manager for setting print options.

Set print options for the scope of the with block, and restore the old options at the end. See set_printoptions for the full description of available options.

Examples

>>> with np.printoptions(precision=2):
...     print(np.array([2.0])) / 3
[0.67]

The as-clause of the with-statement gives the current print options:

>>> with np.printoptions(precision=2) as opts:
...      assert_equal(opts, np.get_printoptions())
