Python -如何向唯一的numpy数组添加数组?每个数组必须表示numpy数组中的一行

I'm a complete beginner in python, and my problem is that i have 4 arrays, with x items:

我是一个完全的python初学者，我的问题是我有4个数组，有x个项目:

persons_id = [ 78694, 51203, ... ]
dates = [ '20072017', '19072017', ... ]
codes = [ 1500, 0606, ... ]
ranges = [ 70, 60, ... ]

What i'm trying to do is ( in a loop ) to produce that kind of output:

我想做的是(在循环中)产生这样的输出:

reporting = numpy.array([persons_id[0],
                        dates[0],
                        codes[0],
                        ranges[0]],
                        [persons_id[1],
                        dates[1],
                        codes[1],
                        ranges[1]],
                        [...])

Thank you in advance

提前谢谢你

Option 1
np.vstack

选项1 np.vstack

np.vstack((persons_id, dates, codes, ranges)).T

array([['78694', '20072017', '1500', '70'],
       ['51203', '19072017', '606', '60']],
      dtype='<U21')

Option 2
np.stack(..., axis=1)

选项2 np.stack(…轴= 1)

np.stack((persons_id, dates, codes, ranges), axis=1)

array([['78694', '20072017', '1500', '70'],
       ['51203', '19072017', '606', '60']],
      dtype='<U21')
