Coding 101 (fun with lists)

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.

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

Functions:
Functions are sections of code (a sequence of executable steps) which we want to be able to use and re-use at many points in our program. It may be that we want to read and process a whole range of data over and over (but the process done to all the data is the same) or maybe there are a number of inputs required from the user which all need to be processed the same way. Rather than rewriting the same lines of code again and again in our program, we can give that section of code a name (known as ‘defining the function’). We can then ‘call’ that named function, that is, ask Python to execute the defined sequence of steps, at any future point within our program, and as many times as we want. (In other programming languages this same functionality may be referred to as sub-programs or sub-routines.) [Read more…] about Coding 101 (part 3)
