What I am about to post is a simple $GOOG chart created by a python script that I grabbed off Trainee Trader’s site. While creating a line chart of GOOG’s stock price is really basic finance, it does represent something very important to me. It means that I’m learning and troubleshooting python at a fast pace.
I just started learning python about a week ago with absolutely no knowledge in programming (except for Frotran 77 a long time ago), but I am armed with an engineer’s logic and enthusiam. I’ve worked on about 15 exercises in a training course I’m taking, and have read up on all the neat things python can do. I installed python 2.6, matplotlib, and the ystockquote module from Cory Golberg on my development machine and configured the correct paths. Then I then tried to copy and paste TT’s google chart python script to see if I could recreate his chart. I typed it verbatim and fired it up in python hoping to see the chart!
Instead of seeing a nice GOOG chart, it crashed on me!!! Yep, it failed and I had no idea what the error messages were telling me.
Fast forward one week and I’m picking up this language quick. So I took TT’s code again, checked out the documentation for the matplotlib module, troubleshot it, and got the damn thing to plot! Go me!
Of course a sophisticated programmer would laugh at my silly plot, but to me it’s awesomeness.
Update: Here’s the revised python script (txt): GOOGChart2.txt
