So I can slice a numpy array quite simply as:
a = np.arange(10)
a[:-3]
array([0, 1, 2, 3, 4, 5, 6])
but now say I do:
a = np.vstack((a, a))
a
array([[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]])
Is there a nice pythonic way (without looping) to get:
array([[0, 1, 2, 3, 4, 5, 6],
[0, 1, 2, 3, 4, 5, 6]])
Thanks.
