replacing pixels in an imagewith pixels from another image python

I am trying to replace pixels less than value 50 in one image (src1) with pixels from another image (src2). The code i am trying is as below. The problem is it is taking lot of time. Can anyone guide me in using optimized way to do this

src1 = cv2.imread('')
src2 = cv2.imread('')
rows, cols, ch = src1.shape
result = src1.copy()    
for i in (xrange(rows)):
     for j in (xrange(cols)):
          k = src1[i,j]
          if (k.all() < 50):
              result[i,j] = src2[i,j]
              cv2.imwrite('',result)

You can use numpy for this.

src1 = cv2.imread('')
src2 = cv2.imread('')
r,c = np.where(src1<50)
src1[(r,c)] = src2[(r,c)]
