•hstack(tup) ,参数tup可以是元组,列表,或者numpy数组,返回结果为numpy的数组。
import numpy as np
arr1 = np.array([1, 2, 3])
arr2 = np.array([4, 5, 6])
res = np.hstack((arr1, arr2))
print res
>>>[1 2 3 4 5 6]
arr1 = np.array([[1, 2],
[3, 4],
[5, 6]])
arr2 = np.array([[7, 8],
[9, 0],
[0, 1]])
res = np.hstack((arr1, arr2))
print res
>>>
[[1 2 7 8]
[3 4 9 0]
[5 6 0 1]]
