I have used id() in production code, but the circumstances were extremely specific: It was in some monitoring-related code that was trying to dig down into the guts of the interpreter for the purposes of tracking memory usage on the level o

When it comes to profiling in Python, never underestimate the power of the standard library's profiler. You can supply it with a custom timing function when instantiating the Profile type [1], and as far as the module is concerned, thi

My own experience was with the 3D-enhanced version of Mechwarrior 2: Mercenaries, specifically. It is possible that the equivalent version for Mechwarrior 2 was more stable. It's also possible my 3D drivers of the time were the cause o

Part of the issue there is that the 3D-acceleration-enabled versions of Mechwarrior 2 (and Mercenaries) were buggy as heck even at the time. (Mercenaries was even pretty buggy before they did the 3D card patch, and it only got moreso.) It

There's a whole generation of games from the mid to late 90s (and perhaps into the early 00s) that's remarkably annoying to play these days because of this issue. The game I've personally tried to get running, every once in a

I am taken a little aback by the name. There is, of course, already the D programming language, which has even had a major version number of 2 for quite some time. It also brings to mind the JavaScript library d3, which, while not strictly

All right, behold my idiotic story about the time I got a job for one of the major tech companies. It's the late 00's. I am in my early 20s. I have an associate's degree from the local community college, and I have been messi

One thing to note, in the gritty details of Python's actual implementation of the list type, is that there's a little more to say about how list resizing works than is immediately obvious. The relevant source is here: https:&#x2F

The standard array module was more relevant in the distant past, before version 2.6 added the bytearray type. Otherwise, numpy arrays are considerably more useful in virtually every circumstance.

Yeah, but we're not talking about pure mathematics. We're talking about floats, and I find that it's very important to be clear about the limitations. It's easy to get some nasty bugs if you start assuming that you can c

This is a neat article, but it does have some errors. One subtle point that the post gets wrong: > So where does that come from? The answer is that Python stores everything inside dictionaries associated with each local scope. Which mean

You joke, but Factorio is a sufficiently "crunchy" logistics game that it has prompted me to study a number of serious topics, from learning linear programming to determine optimal production ratios, to dipping my toe into learnin

I taught myself linear programming because of Factorio. It is easily the single game in which I have spent the most time, probably close to 4,000 hours. It is delightful to see that the team is continuing to improve it, even after the 1.0 r

This is clearly about Python, so I will note that this is not actually the case: The generator expression introduces a new scope, and so it does not reassign the value of x. Python does not require the "global" and "nonlocal&

To be pedantic (which I think is warranted here), range does not return a generator, it returns a sequence called a range object. This object can be indexed, sliced, and (relevant to this discussion) supports the 'in' operator. &q
