In this video, the author shows you how to simplify data manipulation, using advanced containers from the Python collections module.
- [Instructor] There's a lot that we can do…with Python lists and dates,…but in some cases, we need a little more.…The Python Collections module offers several more objects,…all very useful to organize sequences in different ways.…In this video we will learn how to use namedtuple…to describe records efficiently;…use Counter to count identical elements in a sequence;…use defaultdict and OrderedDict to code dictionaries…with default values or ordered keys;…use deque to manipulate double-ended queues.…
As usual, I start by importing all packages…used in this chapter.…We'll play with data about all the gold medals…that were won at the Olympics in athletics.…So we start by reading in a data file.…Before we can parse it, we should understand its structure.…We'll open it in reading mode,…read all the lines, and display only the first 10.…This is simple tabular data separated by tabs, slash t.…The best way to handle tabular data…is a library such as pandas,…which I describe in my course on Introduction…to Data Analysis with Python.…
