If that is the whole statement it will create a new object of class EqualityConstraint and immediately discard it. That may have some useful side effect (for example the object may add itself to a list of constraints) but this is not apparent from this line. hp -- _ | Peter J.

Standard class for time *period*?
Hi, I have been around long enough to know that, due to time-zones, daylight saving and whatnot, time-related stuff is complicated. So even if I think something connected with time should exist, there may well be a very good reason why it does not. My problem: I need to deal with what I call a 'period', which is a span of time limited by two dates, start and end. The period has a 'duration', which is the elapsed time between start and end. The duration is essentially a number of seconds, but in my context, because the durations are usually hours or days, I would generally want to display the duration in a format such as "dd-hh:mm:ss" My (possibly ill-founded) expectation: There is a standard class which encapsulates this sort of functionality. My (possibly insufficiently researched) conclusion: Such a standard class does not exist. What is at fault here? My expectation or my conclusion?

Is it super(UrnaryConstraint, self).__init__(strength) or just the fact that Constraint is its base class? When referring to "self" you are referring to an "instance" of the class or classes, think in terms of objects (the instance, usually self) vs a blueprint (the class, usually cls). saying self.choose_method(mark) checks the "instance" of self to see if it has something called choose_method at run time (instances being created at run time). If you have an instance of just Constraint, and never had a choose_method defined for it, you will get an error because it can't find it (which in this case is presumed as designed). If the "instance" is of a subclass of Constraint that does have a choose_method, that also inherits the stuff from Constraint, it will successfully call it against the "instance" that has been constructed with attributes of both classes. if the instance of a subclass has a definition for something that is in the base class, for instance IF UrnaryConstraint had it's own def satisfy() method, the instance would call the subclass version. In the case given, it does not, so it looks to the parent to see if it has inherited satisfy() from higher up.

Thanks for the examples, but I am not really interested in how to write
a bunch of code to do what I need, as I can already do that. I am
interested in whether there is a standard class for this and, if there is
not such a class, why this is the case.

The Python standard library module datetime seems to be what you want. It has objects representing date/times, and deltatimes (i.e., durations). These can be timezone aware or not as you wish.

What kind of "thread safe" are deque's actually?
A while ago I chose to use a deque that is shared between two threads. I did so because the docs say: "Deques support thread-safe, memory efficient appends and pops from either side of the deque with approximately the same O(1) performance in either direction.” (https://docs.python.org/3.11/library/collections.html?highlight=deque#collections.deque) Earlier today, looking through some server logs I noticed that from time to I’m getting a RuntimeError: deque mutated during iteration I guess this surprised me. When I see “thread safe”, I don’t expect to get errors. Interestingly the error also only started showing up when I switched from running a statistics.mean() on one of these, instead of what I had been using, a statistics.median(). Apparently the kind of iteration done in a mean, is more conflict prone than a median? I’ve got a couple ways I can work around this. But I was surprised. -- https://mail.python.org/mailman/listinfo/python-list

That MAY be a result of threading, but it isn't necessarily. For threaded usage, I would recommend restricting yourself to append/appendleft/pop/popleft (the standard mutators), with any operations on the entire queue being done on a copy instead (either q.copy() or list(q) depending on what you need). The act of taking a copy should itself be thread-safe, and obviously anything done on a separate copy will be independent of changes to the original.

Even without threads, mutating a collection while iterating over it usually results in bad things happening. $ python Python 3.10.10 (main, Mar 5 2023, 22:26:53) [GCC 12.2.1 20230201] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import collections >>> x = collections.deque() >>> x.append(44) >>> x.append(55) >>> x.append(66) >>> x.append(77) >>> x deque([44, 55, 66, 77]) >>> for y in x: x.pop() 77 Traceback (most recent call last): File "", line 1, in RuntimeError: deque mutated during iteration Concurrency just increases the likeliness of mutating while iterating. -- https://mail.python.org/mailman/listinfo/python-list

You don't really have 1000 tabs open at the same time, do you? If you select all the open tabs - I think you wrote that you only have 50 - then you can save them as bookmarks under a folder name you choose. That folder will contain the 50 open links. I tried it this evening, so I know that's how it works. (It happens that I'm working on my own bookmark manager just now, so I've been messing around with importing, exporting, and reading the bookmark files). Then you can export them and import the same bookmark file into another browser on another computer. Whenever you want to reopen some of those tabs, you would navigate to that part of the bookmarks and open the tabs you want. Maybe you have something else in mind? Do you want to send the links of the opened tab set to someone else, but not all your bookmarks? Please explain more carefully what you want to do. -- https://mail.python.org/mailman/listinfo/python-list

Load Firefox's HTML format bookmark file into Notepad++. View it in a browser using the "View/View Current File In" menu item. True, you could have opened it directly in the browser, but now you can edit the file and cut out the parts you don't need, and check to make sure you get what you intended. The structure of the HTML is very regular. If you have saved your set of opened links under a distinctive heading near the top of the collection - as I suggested earlier - it should be easy to find the start and end points of their HTML elements, and delete all the ones you don't want. You could import this shortened bookmark file into another installation of Firefox and this would add them to the bookmarks in the other browser, all grouped by your custom heading. -- https://mail.python.org/mailman/listinfo/python-list
