Thank you Rachel and Alan for the feedback. Oddly enough, I had created an exception between the time I sent this and your response to catch occasions when the list is empty (I will need to test a few other things, like what if the list holds items other than strictly numbers?) I did utilize some

[Tutor] Python Extensions in C

Hello All: As an intellectual exercise, I wanted to try my hand at writing some extensions in C. I was wondering if you all could look over my code and give some feedback. Here is the link for the code: http://pastebin.com/jw3ihfsN I have zero experience coding in C (and not much more coding in

We just had a similar question yesterday. Just make sure Python is on your PATH. CD to the directory where your file is located and then you can just type "python myfile.py" where myfile is the name of your file. On Fri, May 20, 2011 at 1:43 PM, michael scott wrote: > Okay, my title might be und

concatenate the entire thing together, including the "*". Once you have that as a single string, use string.split('*') and you will have your two strings. On Mon, May 16, 2011 at 9:51 AM, Spyros Charonis wrote: > I have a file with the following contents: > > >from header1 > abcdefghijkl > mnopq

Slow day at work, so I tried something a little different mostly as a learning exercise for myself, let me know what you all think. I thought it would be useful to have a writer that scales and that organizes the data. For example, you might have 20 tests one day, and 5 the next. I broke up the d

I double clicked it from my desktop and it opens just fine (though I didn't attempt to run it, because I have 2.6 on my work machine and I'm sure that will cause it to fail). Have you added python to Path environment variables in windows? On Wed, Apr 13, 2011 at 11:14 AM, Gary Beynon wrote: > -

At least in my case it was about simplicity.

Re: [Tutor] counting a list of elements

The nice thing about Python is you don't have to build things from scratch, and I imagine most people would discourage on account of it being a waste of time, other then education value. But the "best practice" in my humble opinion would be to use the built in len function. If what you are after i

For all of these, I wrote my own class with methods to create the correct output. there is not built in python functionality that I know, although there may be a package. For IRR, the method expects a list and at least one negative value. I believe the way I did NPV was a dictionary, where the key
