Notice that the reshape function creates a new array and does not itself modify the original array. Keep in mind that Python's name-binding approach still applies to arrays. The copy function can be used to create a new, separate copy of an array in memory if needed: >>> a = np.array([1, 2, 3], float) >>> b = a >>> c = a.copy() >>> a[0] = 0 >>> a
