NumPy Fundamentals • Why Numpy? • Remember that Python does not limit lists to just elements of a single class • If we have a large list and we want to add a number to all of the elements, then Python will asks for each element: • What is the type of the element • Does the type support the + operation • Look up the code for the + and execute • This is slow

NumPy - Array Creation Routines A new ndarray object can be constructed by any of the following array creation routines or using a low-level ndarray constructor. numpy.empty It creates an uninitialized array of specified shape and dtype. It uses the following constructor − import numpy as np x = np.empty([3,2], dtype = int) print x

hence can deal with int, float, double and NumPy array datatypes. Arbitrary precision arithmetic is not supported and the basic numeric types are con-verted into their C counterparts. NumPy array accesses are converted into C array accesses. Cur-rently “long” integers are not supported but will be added after transition to Python 3. 2.
