In Chapter 2, Working with the NumPy Array As a First Step to SciPy, we will guide you through basic object creation in SciPy, including the best methods to manipulate data, or obtain information from it. [ 21 ] Working with the NumPy Array As a First Step to SciPy At the top level, SciPy is basically NumPy, since both the object creation and basic manipulation of these objects are performed by functions of the latter library. This assures much faster computations, since the memory handling is done internally in an optimal way.

We use it only when we need to change the values of flattened arrays. We will highlight the power of the sorting methods in the following code snippets. When sorting an array of integers, what would be the order of their indices? We may obtain this information with the argsort() method. We may even impose which sorting algorithm is to be used (rather than coding it ourselves)—quicksort, mergesort, or heapsort. We can even sort the array in place, using the sort() method. sort() >>> print(A) The output is shown as follows: [10 11 12 13 14 15 16 17 18 19] Object calculations Array calculation methods are used to perform computations or extract information from our data.
