如何打印/返回多维数组中的值？

Question

Hi I have been working on opencv-python with opencv 3.0.0 and python 2.7.x

import numpy as np
import cv2

img = cv2.imread('C:\\Users\\J\\Desktop\\image.jpg')
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

corners = cv2.goodFeaturesToTrack(gray,25,0.01,10)

print corners

this is returning me

[[[ 335.  263.]]

 [[ 306.  254.]]

 [[ 337.  253.]]

 [[ 349.  262.]]

 [[ 507.  361.]]

 [[ 300.  264.]]

 [[ 420.  250.]]

 [[ 362.  252.]]

 [[ 375.  261.]]

 [[ 322.  254.]]

 [[ 409.  260.]]

 [[ 545.  294.]]

 [[ 505.  398.]]

 [[ 388.  252.]]

 [[ 493.  315.]]

 [[ 578.  376.]]

 [[ 480.  376.]]

 [[ 510.  375.]]

 [[ 396.  261.]]

 [[ 493.  376.]]

 [[ 532.  376.]]

 [[ 575.  357.]]

 [[ 540.  360.]]

 [[ 514.  307.]]

 [[ 401.  251.]]]

I know this is a multi-dimensional array and how can I print the values in this array in the form of (x,y) ? I think there is a simple answer for this but it has been quite a long time I have used python. Thanks in advance !

import numpy as np
import cv2
img = cv2.imread('C:\\Users\\J\\Desktop\\image.jpg')
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
corners = cv2.goodFeaturesToTrack(gray,25,0.01,10)

corners = np.int0(corners)
for corner in corners:
    x,y = corner.ravel()
    print(x,y)
