This code is free, use it as you like. I just wanted to present it to show what I’ve been messing with. I have an idea for this at work. I haven’t messed with classes yet, but that’s next on my agenda.

import mailbox
import sys
import os

months = {'Jan': '01', 'Feb': '02', 'Mar': '03',
		  'Apr': '04', 'May': '05', 'Jun': '06',
          'Jul': '07', 'Aug': '08', 'Sep': '09',
		  'Oct': '10', 'Nov': '11', 'Dec': '12'}
emails = {}
total = 0

def accumulate_counts(email):
	for message in email:
		date = message['date']
		split_date = date.split()
		day = split_date[1]
		month = split_date[2]
		year = split_date[3]
		monthnum = months.get(month, 0)
		yearmonth = year + monthnum

		count = emails.get(yearmonth, 0)
		if (count == 0):
			emails[yearmonth] = 1
		else:
			emails[yearmonth] += 1

mbox_path = sys.argv[1]

for root, dirs, fileNames in os.walk(mbox_path):
	for fileName in fileNames:
		path = os.path.join(root, fileName)

		mbox = mailbox.mbox(path)
		accumulate_counts(mbox)

for m, e in emails.iteritems():
	print m, e
	total += e

print total

Comments are welcome, just be gentle. I know some variables are short, but I’ll fix that up on the next iteration

My Django experiment is going relatively well. The database model is done, and now I’m at the point where I’m a bit stuck. I’m still learning my way around the framework, so I’m sure I’ll get it with time. What I’m currently dealing with right now is trying to figure out views. The way I understand it so far is that urls.py defines what happens when you go to a particular URL for the project, such as http://project/view/main_page, then in views.py there would be a main_page routine. Part of my hang up right now is the design aspect. In a nutshell, I’m trying to retrofit an old PHP application into Django while not altering it too much. I’m in no hurry to finish this, so I have time. As far as personal projects, I don’t really have any Django-related projects I could work on for personal things, so I’ve been thinking about some ideas I can do in just normal python. PyGame seems rather interesting, and of course I could always find some other project to get into as well. If you have any thoughts on projects looking for a semi-new Python guy, drop me a comment.

At any rate, learning more Python via Django seems to be going well so far. I am branching out, though, trying some new things and playing with some libraries. I’ll share some of my things when I finish.

As far as personal projects go, there’s not really a whole lot I’ve found to code up. I’ve thought of a couple of things, but never really got into them. I should, though, so I can sharpen my skills. I’ll be working on the work projects at home mostly, but I want to have something I can do for myself, or if nothing else, something else to help out on. Hopefully in 2008 I’ll be a bit more inclined to write more code.

In more domesticated news, I made some lasagna over the weekend, following a recipe in one of the fatherhood books I’ve been reading. Other than the tomato sauce being more meat than tomato sauce, it turned out pretty well. I think with a bit of fine-tuning (and a proper lasagna pan), it will be even better the next go round. I’m trying to do all I can around the house for Beth while she’s pregnant. Granted, she’s a big girl and can still take care of things, but it’s my way of contributing to the pregnancy as a whole.

As far as geeking out goes, I’ve been playing around a bit with Python and now Django. Django is a Python-powered web framework, and while I should probably wait until I have a few regular python scripts under my belt, I couldn’t resist the urge to install it and play around with it. Surprisingly, it’s pretty straight-forward, and my understanding of Python seems to be a bit more solid than I thought. My main issue is using Python. Once I get to using it more often, I’m sure things will start to become second nature to me.

Oh, and one other thing. Bethany and I will be heading up to PA for Father’s day. I’m not sure what all we’ll be doing, but I would imagine we might have a bit of time to meet up with some of my PA friends at some point during the weekend. That should be pretty fun, I’m thinking. She gets to meet my family, I get to take her around my old stomping grounds, and I get a vacation from work. Sounds like the perfect little getaway to me.
