Coding 101 (fun with lists)

coding-101-fun-with-listsThis 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.

spaghettiWhen strings become spaghetti:
Working with strings and files, particular when using the for {line} in {filehandle}: construct, allows us to do some cool manipulation of data, by finding, splitting and stripping the data into different chunks based on some repeating factor (such as a comma spearating each value in order), then sorting, counting and totalling those values through iterative loops.

This post follows on from earlier posts (Coding 101 (part 1) ~ (part 2) ~ (part 3)) and records my responses and learnings from the highly-recommended Python programming book and Coursera specialisation by Charles Severance (see References below).

A quick recap on strings:
Strings are computer-speak for characters, specifically where some object or value has the ‘type’ string. Type is an attribute Python applies to any given object or value so it knows how to handle that object or value, i.e. what kinds of operations can and cannot be applied to it. String, and two numeric types – integer and float – are the most common types within Python.

A string may contain one or more characters, so ‘a’ and ‘0’ are strings, just as ‘abcdefghij’ and ‘Hello world. I am Python.’ are. [Read more…] about Coding 101 (part 4)
