The code is found in the file integration_​methods_​vec.​py.

Let us test the code interactively in a Python shell by computing . The file with the code above has the name integration_methods_vec.py and is a valid module from which we can import the vectorized function:

Note the necessity to use exp from numpy: our v function will be called with x as an array, and the exp function must be capable of working with an array.

The vectorized code performs all loops very efficiently in compiled code, resulting in much faster execution. Moreover, many readers of the code will also say that the algorithm looks clearer than in the loop-based implementation.
