创建垂直二维 numpy 数组

Question

first_name = [["Tom", "Alex", "Sam"], ["Anna", "Bob", "Mike"]] 
last_name = [["Smith", "Brown", "Lee"], ["Davis", "Allen", "Lewis"]]

我想创建一个vertical numpy数组，输出如下：

[["Tom Smith"    "Anna Davis"]
 ["Alex Brown"   "Bob Allen"]
 ["Sam Lee"     "Mike Lewis"]]

我该怎么做？

Answer 1

尝试：

out = np.array([[f'{c} {d}' for c, d in zip(a, b)] for a, b in zip(first_name, last_name)]).T
print(out)

印花：

[['Tom Smith' 'Anna Davis']
 ['Alex Brown' 'Bob Allen']
 ['Sam Lee' 'Mike Lewis']]
