I have a field in my module that is used to hold the status of the object. So far I have used: ORDER_STATUS = ((0, 'Started'), (1, 'Done'), (2, 'Error')) status = models.SmallIntegerField(choices=ORDER_STATUS) Its easy to convert one way: def status_str(self): return ORDER_STATUS[self.status][1] The problem is when updating. I find...
I am using Jinja2 to generate HTML files which are typically very huge in size. I noticed that the generated HTML had a lot of whitespace.

When I say "minimize", I mean remove unnecessary whitespace from the HTML (much like Google does -- look at the source for google.com,...

I personally don't run any of my apps in optimized mode, but it feels like I should stay away from assert just in-case. It feels much cleaner to write assert fi...

I'd like to do some statistical analysis on it, pull out some sample data, plot general trends, do variance and R-square analysis, and plot some spectra diagrams. For now, I'm considering numpy for the analysis. I was wondering what issues should I expect with such large files...

Right now I haven't made any way to save the levels, but I thought a simpler solution would be to just reuse the seed used by Python's random module. However I've tried using both random.seed() and random.setstate() and ...
