Python Numpy array conversion

Question

I've got 2 numpy arrays x1 and x2. Using python 3.4.3

x1 = np.array([2,4,4])
x2 = np.array([3,5,3])

I would like to a numpy array like this:

[[2,3],[4,5],[4,3]]

How would i go about this?

Answer 1

You can use numpy.column_stack:

In [40]: x1 = np.array([2,4,4])

In [41]: x2 = np.array([3,5,3])

In [42]: np.column_stack((x1, x2))
Out[42]: 
array([[2, 3],
       [4, 5],
       [4, 3]])
