Re: Variables in a loop, Newby question
Hello everyone, I have been away for a while. I have been reading all the good advises and want to explain why I want to read the temperatures separately from the main script. It takes a long time to read out 10 temperatures. About 10 seconds. So that’s the reason why I had the idea to create a separate script and I thought by making te variables Global I could access them by other scripts. Now I know that’s not the purpose of Global. Maybe I can create a loop that keeps running simultaneously with the rest of the script. I’ve downloaded a great student book about Python and learning a lot. Thanks for all the answers and I’ll post more questions in the future, I’m sure of it. Greetings Robert -- https://mail.python.org/mailman/listinfo/python-list

That's true except for the "comes out" part. Just because python.org has released a newer 3.x Python doesn't mean everyone has it; Debian Wheezy (the current stable) ships with 3.2, and Debian Squeeze (the current oldstable, still supported and will be until some time 2014 probably) ships 3.1. So for scripts that need to be deployed onto one of the most popular Linux distributions, supporting only 3.3 is pretty much out of the question. And Red Hat, generally, is supported for even longer. I don't know what Python versions are going to still be around for the next ten years, but the easiest way to check would probably be to see what RHEL support dates and Python versions are. However, I do broadly agree. For controlled environments, you should be able to slide from 3.1 to 3.2 to 3.3 to 3.4 on whatever schedule you choose, and happily drop support for the older versions. But in less controlled environments, that's a bit harder. Probably within the next 5 years, it'll become reasonably plausible to support nothing older than 2.6, and then all those 3.x compatibility __future__s will be all you need. Well, most of what you need. There are still fundamental issues with functions not taking Unicode strings, but that's going to be a problem whatever you do. But life'll be a lot easier.

The *first* question you have to ask is, which third-party libraries do I rely on? Those libraries will set the minimum system requirement. Beyond that, you have total freedom to support as many or as few versions as you like. Ask yourself: - Which operating systems do I intend to support? If the answer is "Windows only", you pretty much can pick whichever version of Python you like, since all versions of Python are equally difficult (or easy) to install on Windows. Likewise for Mac. If the answer includes Linux or Unix, then the next question to ask is: - Shall I support only the OS-provided version(s) of Python? If so, then you need to work out which version(s) of Python are common to all the OSes you intend to support. E.g. there are currently supported versions of Centos and RHEL that provide Python 2.4. If you intend to support those versions of Centos and RHEL, then you need to support Python 2.4. If you are prepared to drop support for such systems, then you can drop support for 2.4 and move on to 2.5 or 2.6. It depends on how much extra effort you wish to go to in order to support what percentage of your users. Personally, I find it very annoying when vendors expect you to upgrade perfectly adequate, still supported systems, and so I try to target 2.4+ when I can. (Also, I am still running a Centos system with 2.4, so I'm scratching my own itch.) On the other hand, I once tried to target Python 2.3+. That decision lasted about two days. The amount of functionality missing from 2.3 compared to 2.4 makes it too painful. Alternatively, if you don't care about the OS-provided Python (perhaps you're providing your own, or you expect your users to install from source), then I think it is acceptable to target 2.7 and 3.3 or better (e.g. drop support for 3.1 and 3.2). 3.0 is not supported at all -- it was a buggy release and was quickly dropped for 3.1. If you're not constrained by "yum python3" or "apt-get python3", then 3.3 is probably the version you should aim for. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

I'm quite happy to work with a 3.4 alpha, but when it comes to installation instructions, "get this and compile it" is a lot less helpful than "install python3 via your OS package manager" (especially since compiling Python from source also means getting the development versions of whatever modules you need - apt-getting a bunch of -dev packages, or whatever - and if you don't get them, some modules mightn't work even though core Python does). Hence I'd like to stick to OS-provided versions *where reasonable* - I'm not going to warp my code around Python 2.4 unless there's a large slab of users on that, but I will restrict myself to Pike 7.8.700 because it's worth the effort.

By this I mean that, whenever I find that I need to install another package, it shows up as Python 2 unless I explicitly specify Python 3. What's the deal? If I want to make a distributable software package, should it be 2 or 3? Enquiring minds want to know. Choosing between 2 and 3 should be done the same way any version decision is made: examine all of your dependencies (libraries, help online, skilled helpers available, hosting options, books, etc), then choose the highest version that supports them. Some people still find that the answer is 2, but many are finding that it is now 3. There's a lot of FUD about Python 3, don't listen to it. Certainly don't be thrown by the "default" of 2. It doesn't matter what most people do, or how your operating system is configured, what matters is whether you have what you need. Note that on sensible operating systems, "python" will continue to mean Python 2, and "python3" will mean Python 3. This will help perpetuate the notion that Python 3 is the outlier, but it's the only way to keep software working properly. Don't let it color your perceptions. If you are going to support both 2 and 3, in addition to the other good suggestions in this thread, the six module on PyPI can help with the differences. -- Ned Batchelder, http://nedbatchelder.com -- https://mail.python.org/mailman/listinfo/python-list

String Template
Hello I'm rewriting a program previously written in C #, and trying to keep the same configuration file, I have a problem with untapped strings. The previous configuration files provide an input template string of this type: This string is parsed and the values are replaced with the actual values written to a log file (apache), then he is given the variable name. Taking for example a classic line of apache log: 0.0.0.0 - [27/Dec/2013: 00:56:51 +0100] "GET / webdav / HTTP/1.1" 404 524 "-" "Mozilla/5.0 (Windows, U, Windows NT 5.1, en-US , rv: 1.9.2.12) Gecko/20101026 Firefox/3.6.12 " Is there any way to pull out the values so arranged as follows: ip = 0.0.0.0 date = 27/Dec/2013: 00:56:51 +0100 url = / webdav / Tnx -- https://mail.python.org/mailman/listinfo/python-list

That seems odd.) One common way to implement this sort of thing is with a regular expression. You can either derive a regex from your config file, or have users directly manage the regex. For the specific case of parsing the Apache common log format, there's plenty of material around. This page [1] has a tidy regex that'll do the job, and this module [2] purports to create a parser by reading the configuration line that creates it. I don't know anything about either, save that they came up in a Google search for 'python apache common log', along with a whole lot of other decent-looking results. But for a more general solution - supposing you have piles and piles of those parser strings - I'd be inclined to write a preparser that reads your config file and derives regex patterns. It needs to figure out what's a placeholder and what's literal text, then escape the literal text (if there are regex metacharacters in it) and come up with some sort of capturing sequence for the placeholder. I don't know what you'd want there; possibly (.*?) will be the best (that means "capture any number of characters, as few as possible"). But you know your data far better than I do.

Why can't you run it that way? What does "got nothing" mean? Did you just get another shell prompt back with no output? Did your shell window close? Did the machine crash? I asked you to run these commands: > cat /etc/lsb-release > > uname -a > > python --version Did you run them? What output did you get? I know it seems silly, but it really is important that people know exactly what your environment is. The less information we have, the harder it is to figure out what's going on. > but here is all the code relevant to this issue: Well, you've got a lot of code there. What you want to do is reduce this down to the smallest possible amount of code which demonstrates the problem. I can't even begin to run your code here because I don't have gnuradio installed. It's almost certainly not necessary to demonstrate the problem (nor are posixpath, cPickle, wx, etc), but I can already see that as soon as I delete those, I'll run up against the next problem, which is that update() is a method of a class and I don't have the rest of that class. Let's take this one step at a time. You've got: self.logfile.write('%s\t'%(time.time())) which is apparently causing, "1388164053.18", to end up in your output file. The question is, why are there only two digits after the decimal place? Possible causes: 1) Your version of time.time() is returning a float which is only precise to the centisecond. 2) Your version of string's %s operator is only converting floats to two decimal places. 3) Your self.logfile.write() method is taking the string it was given and stripping off all the digits beyond two after the decimal point. All of those seem about equally unlikely, so just start to eliminate them one by one. What happens if you do: self.logfile.write("1388164053.183454") What happens if you do: t = time.time() self.logfile.write("str=%s, repr=%s", (str(t), repr(t))) what happens if you get rid of the whole self.logfile.write() thing and just use print? If you're working in some environment where stdout gets redirected somewhere that you can't find, bypass stdout completely: my_file = open("/tmp/foo", "w") print >> my_file, time.time() and then go look and see what got dropped into /tmp/foo. -- https://mail.python.org/mailman/listinfo/python-list

However, I have since figured out exactly what's going on. I'm going to do you a favor and NOT tell you what I've figured out (because you won't learn anything that way), but I will give you a hint. The hint is that if you run the two lines of code I suggested above, the answer should be obvious.
