Numpy zip function

Stack the input arrays depth-wise using numpy.dstack() and get rid of the singleton dimension using numpy.squeeze() and then assign the result to co-ordinate variables x1, x2, and x3 as in:

In [84]: x1, x2, x3 = np.squeeze(np.dstack((x,y)))

# outputs
In [85]: x1
Out[85]: array([ 1, 11])

In [86]: x2
Out[86]: array([ 2, 22])

In [87]: x3
Out[87]: array([ 3, 33])

Just use

x1, x2, x3 = np.vstack([x,y]).T
