数组——如何在Python中堆叠3D列表中的元素

我有两个类似的清单：

x = np.array([1,2,3,4,5])

y_all = [[2,3,5,4,6], 

         [3,2,4,3,5], 

         [4,5,4,3,4]]

我需要输出如下：

[(1, 2), (2, 3), (3, 5), (4, 4), (5, 6), (1, 3), (2, 2), (4, 3), (5, 5), (1, 4), (2, 5), (3, 4), (4, 3), (5, 4),]

我怎样才能更有效地做到这一点，如果我有一个更大的x和y_，我就可以做到这一点？

这就是我迄今为止所尝试的：

import numpy as np

y=np.array(y_all).T

y_all_fin = []

for i in range(len(y[0])):

    inter = np.vstack((x,y_all[i]))
    y_all_fin.append(inter)

points = np.hstack((y_all_fin[0],y_all_fin[1],y_all_fin[2])).T

N = []

for i in range(len(points[:,0])):

    new = tuple(points[i])

    N.append(new)
