如何从数组元组创建数组或ndarray

Question

说我有没有

s=np.zeros((5,5))
array([[ 0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.]])  #which is an ndarray

s2=[s[ix,1] for ix in range(2,5)],[s[ix2,1] for ix2 in range(2,5)]
([0.0, 0.0, 0.0], [0.0, 0.0, 0.0]) #which is a tuple

如何将s2变成数组或ndarray？先感谢您。

显而易见，请使用np.array()

s2 = np.array(s2)
