For basics, refer to Part I. Vectorization First let’s revisit how we would do any arithmetic operation on all the elements of list (Python in-built container). Looping through all the elements is probably the only way to go about it. The neatest syntax is using list comprehensions. # List Comprehension >>> L = [1,2,3,4] >>> [i * 2 for i in L] # list comprehension [2, 4, 6, 8] Now imagine doing this for a multi-dimensional list of data and think about the readability. https://chintak.sh/posts/2013-07-15-numpy-the-tricks-of-trade-part-i/ Mon, 15 Jul 2013 00:00:00 +0000 https://chintak.sh/posts/2013-07-15-numpy-the-tricks-of-trade-part-i/ This post aims to highlights some of the basic features of NumPy which gives it an edge over Python in-built containers for computational purposes. The next post will talk about some advanced and more fascinating features of NumPy. NumPy is an extension package for performing efficient manipulations in multi-dimensional data. The numpy array object is extremely efficient at handling such arithmetics and provides vast support for basic and advanced manipulations.
