4088 | Some tips and techniques for huge data handling in Python Python's an excellent tool for handling huge data sets and long-running programs, although some of the elements of the language that you'll use for such work aren't exactly things we teach on our Introduction to Python courses. Yesterday, however, I was teaching an Intermediate Python course, and had ... | 2013-05-18 |
3766 | Python timing - when to use a list, and when to use a generator If you're going to cook dinner for the family, it's much more efficient to cook everyone's meal together.

2462 | Python - how it saves on compile time Python is interpreted every time you run the code ... or that's the simple first story you're told. But really it's not that simple ... and not that inefficient.
When you run a Python program, it is not interpreted line by line as you run it - it is interpreted all at once before it's run at all, ... | 2009-10-20 |
2369 | Using a cache for efficiency. Python and PHP examples Ask yourself "how long is it (in seconds) from 5.36 a.m. and 20 seconds to 6.04 a.m. and 39 seconds".
Have you worked that out?
Now - how long is it (in seconds) from 5.36 a.m. and 20 seconds to 6.04 a.m. and 39 seconds.
Got that? And how long is it (in seconds) from 5.36 a.m. and 20 seconds to 6.04 ... | 2009-08-23 (longer) |
2277 | Python classes / courses - what version do we train on? Usually, the release number of a programming language that's used on a 'first level' course doesn't make a big difference as the changes tend to be quite minor - after all, languages cannot change much for who would develop e piece of code using a syntax that was likely to go out of date? But that's ... | 2009-07-11 |
