Building a Tagging Engine in Python using Dictionaries

01/05/2016 By debkr

I started playing around building a Tagging Engine in Python using Lists but now I’ve studied a bit more – particularly Dictionaries – I want to see how I can perfect what I was working on. Here are a couple of key things I added/changed in this program over the version I was working on earlier.

1. Using a dictionary instead of lists for faster counting and simpler recall. This is straight forward, using the get method as taught by Dr. Chuck (see Coding 101 part 7 for more details).

words = dict()
for word in wordlist :
____if word in excluded : continue
____words[word] = words.get(word,0) + 1

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.
