Coding 101 (fun with lists)

18/04/2016 By debkr

This is me just mucking about with lists, testing out what I’ve learnt so far and applying it to little problems I might want to solve. I find it the best way to learn, and it’s more fun than reading books!

Project 1: Building a tagging engine (Mon 18Apr16)

1. This snippet splits each line into a list, creates an iteration variable to loop through all words in the line list and print them out. I add various print statements at suitable points (both variable print statements and descriptive text statements) to help me test the program structure, to make sure it’s doing what I want and expect it to at each point through the loop.

This post follows on from earlier Coding 101 posts and records my responses and learnings from the highly-recommended Python programming book and Coursera specialisation by Charles Severance (see References below).

Opening data files:
In all our previous examples we used data as a constant (i.e. hard-coded into the program some way) or we prompted the user to enter some data which was then manipulated by the program in some way. We want to be able to read data from a variety of sources though – either from files, or from the web – and we know these are going to be much larger data sources, so we’ll need to be able to access and save files on our hard drive somewhere.

This post follows on from my earlier post Coding 101, and is my responses and learnings from the highly-recommended Python programming book and course by Charles Severance (see References below).

Jargon:
I’m working on a glossary here, but still very unstructured and massively incomplete so I suggest staying with Google for now .

Some necessary concepts:
Programming consists of sentences or statements, which may include reserved words, which tell Python what we want it to do, but will also include some values in both numerical and text formats. These take the form of either constants, whose values don’t change, and variables, [Read more…] about Coding 101 (part 2)

A word before I begin
You can do no better in learning Python programming for data handling/analysis than to study for yourself one of Charles Servance’s MOOC’s, or to download and work through his freely-available, ‘remixed’ open-source book (see References below for links to both). I am not even standing of the shoulders of giants here… I am merely scurrying along way behind them all, picking up what few crumbs of knowledge and wisdom I can along the way. Blogging my own educational journey – as a 40-somthing woman heading into the world of tech – is a way to help me consolidate my own learnings. If it can help you too – above all by showing empirically that “if she can, then I can” – it will have served a double purpose. [Read more…]
