Is there a numpy operation that does the following to the array?

Thanks in advance.
How about:
import numpy as np
a = np.array([[1,2],[3,4]])
a
array([[1, 2], [3, 4]])

How about:
>>> import numpy as np
>>> a = np.array([[1,2],[3,4]])
>>> a
array([[1, 2],
[3, 4]])
>>> a[::-1, ::-1]

How about
>>> a
array([[1, 2],
[3, 4]])
>>> a[::-1].transpose()[::-1].transpose()
array([[4, 3],
[2, 1]])
Or did you mean
>>> a.reshape((4,))[::-1].reshape((2,2))
