Converting a Numpy One-Dimensional Array to Two Dimensions

Lets say we have created a 1-dimensional array in Python using numpy, that is,

import numpy as np
x = np.array([1,2,3])
print x.shape
>> (3,)

This array is one-dimensional and wow we want to convert that array into a two-dimensional object. To do it we can do either

x.shape = (1,-1)

or

x = x.reshape(1,-1)

If we want to transpose it at the same time we just flip -1 and 1,

x = x.reshape(-1,1)
