combine numpy arrays element by element? [duplicate]

Question

I'm not sure what the proper terminology is for this but I would like to combine two arrays such that the resulting array has paired each item from A with each item from B:

A = [1, 2, 3]
B = [1, 2, 3]

result = [[1,1],
          [1,2],
          [1,3],
          [2,1],
          [2,2],
          [2,3],
          [3,1],
          [3,2],
          [3,3]]

Is there a numpy method for accomplishing this or do I need to generate a for loop and build a whole new array?

Generate that using:

[(x,y) for x in A for y in B]
