When should I use "parent=None" in __ini__ and "parent" in super()
by Mohsen Owzar Sept. 2, 2022

Sept. 2, 2022

Hi Guys I'm writing since almost one-year codes in Python, using TKinter and PyQt5. I'm somehow able to writes GUIs in both of them. But since I'm using more Pyqt5 and using classes with initialization and super() constructs, and also I saw lots of videos and examples of coding them, I still don’t know exactly how and when should I use the parent in __init()__ and super() construct. For example, the following lines use "parent=None" in the __init__ construct and "parent" in the super() construct. And sometimes I do not see any of them in these two constructs. :::::::::::::::::::::::::::::::::::::::::::::::: class MyClass1(QWidget): def __init__(self, name, parent=None): super(MyClass1, self).__init__(parent) print(self.parent().test) :::::::::::::::::::::::::::::::::::::::::::::::: And sometimes without "parent" like the following: :::::::::::::::::::::::::::::::::::::::::::::::: class MyClass2(QWidget): def __init__(self, name): super(MyClass2, self).__init__() print(self.parent().test) :::::::::::::::::::::::::::::::::::::::::::::::: Could anyone explain this to me when and for which action I have to use the first one "MyClass1" and when the second one "MyClass2"? Regards Mohsen

googletrans in python
by Quentin Bock April 4, 2022

April 4, 2022

Can someone explain the basics of googletrans in python? I want to make a program that translates stories into English, but I'm not sure how to get a translation printed. Also, is this needed to be done in an HTML file inside python? If so can someone provide basic code for a translation and how that should be written and work? Thank you

Skip: being you a Python old timer, I think you are just grumbling for no good reason. :) Before anything else, people are already jumping into implementation details, optimization, syntax, etc. I am barely starting to look at whether there have been previous existing efforts, and if so, why were they discarded, etc. > > What exactly have you given me that I couldn't have done with > > x = 1 > x += 1 > I come back again to repeat it one more time: the compile() function already exists and works in Python. Before you do your posting, please think about the compile() function first. (Do I need to say it one more time? I don't mind.) So, let me try to pretend I am Skip Montanaro, and follow through with the process. (a) OK, I have been told that compile() function exists in Python. (b) I am complaining that I can do x = 1 x += 1 without resorting to codeblocks. So there is no need for codeblocks. Codeblocks are useless, good for nothing. (c) OK, one more time, I have been told that compile() function exists and works in Python. Everytime I talk about codeblocks, I need to think about the compile() function first. (d) Aha! So by analogy, there is no need for the compile() function in Python. I get it now! (e) Wait a second... searching through the Python newsgroup archive I find hundreds if not thousands of messages related to the usage of the compile() function. So the compile() function can't be useless. Either thousands of Python users are wrong, or I have not been careful in my thinking process. (f) Hmm... let me look at those messages and try to understand how people are using the compile() function. (g) Aha! The compile() function is not useless. I know how to use it, now. (h) Aha! Codeblocks are not useless. (i) Aha! So codeblocks are analogous to the compile() function, the only difference is that codeblocks are compiled at compile time. The compile function compiles the code string at runtime. (j) Wait, I think Hung Jung has said everything before in his messages. Bingo! Now you get it. Hung Jung

mac app from a python script?
by Dan Stromberg March 6, 2022

March 6, 2022

Hi folks. I have a Python 3 script (built on top of gi.respository.Gtk) that runs on Linux and macOS 11.5. It's at https://stromberg.dnsalias.org/~strombrg/hcm/ if you're curious. It works the way I want on Linux, but on macOS I seem to have to start it from the command line, like: hcm --gui ...because I don't know how to create a macOS "app" that goes under /Applications. I don't really care about having a single executable on macOS, and I don't really care about creating a .dmg or .pkg file. I'd be perfectly happy just running "make install" and putting a #!'d script under /Applications with appropriate metadata - but if it's easier to do a single executable, .dmg or .pkg, I'd be fine with that. I've experimented with a few different options for this (months ago), mostly py2app, but it doesn't appear to like gi.repository.Gtk much. What's the most straightforward way of installing a Python script under /Applications on macOS? I'd -love- to find a way of doing something analogous to Linux' desktop-file-install - that is, something that isn't click-happy, but GUI's are acceptable too if they'll get the job done. Thanks!

Getting Syslog working on OSX Monterey
by Philip Bloom March 6, 2022

March 6, 2022

Hello, First time mailing and looking for help/guidance. Hopefully not too in the wrong place. We've had an app with logging to a /var/log for many years through logging.sysloghandler. Recently, though, I noticed that it suddenly was getting no logs whatsoever over there and investigated, believing the recent triggering change was upgrading to Mac OSX 12 (Monterey). My understanding is a bit primitive, but our config had never been hard to follow previously and I may be missing something fundamental. I've looked over a number of online examples but they don't seem to be running correctly either. I'm on Python 3.6.8 (though we're about to start an upgrade to the latest stable, if that in theory may have changes to syslog handling). I'm mostly ending up here since I'm finding such differences in response between python modules I'd expect to be fairly similar. Separating into a test script I've been testing with logging.SysLogHandler, syslog, and the command line 'syslog -s'. Replaced all below with a placeholder appName but it's normally a fairly unique setupCDNGUI name. Example with syslog (python module): - This will show up in System.log but not in Apple's Console for all messages to device, though won't get all the way to file. import syslog syslog.syslog(syslog.LOG_NOTICE, 'AppName: THIS IS A TEST - Processing started') syslog.syslog(syslog.LOG_ERR, 'AppName: THIS IS A TEST ERROR - Processing started') Example with SyslogHandler: - This doesn't seem to show up anywhere besides the screen log, which is odd to me as reading the docs, I understood this to be a logging integration into the syslog module, so expected similar behavior in at least what was sent out. Syslog handler is definitely picked up in logging.handlers root_logger = logging.getLogger() root_logger.setLevel(logging.DEBUG) basic_datefmt = '%m/%d/%Y %I:%M:%S %p' formatter = logging.Formatter(fmt='%(asctime)s %(levelname)s: %(message)s', datefmt=basic_datefmt) syslog_format = logging.Formatter(fmt='SetupCDNGUI: %(message)s', datefmt=basic_datefmt) scrhandler = logging.StreamHandler() scrhandler.setFormatter(formatter) root_logger.addHandler(scrhandler) sys_handler = SysLogHandler(address='/var/run/syslog') #sys_handler.encodePriority(SysLogHandler.LOG_USER, SysLogHandler.LOG_ALERT) # Tried with the above, but didn't make a difference. Neither did not defining the address and letting it go to local host. sys_handler.setFormatter(syslog_format) root_logger.addHandler(sys_handler) logging.critical("This is a test") logging.error("This is a test error") logging.info("Still a test") logging.debug("Testy test") Using command line: Oddly, this gets to Console.Apps messages from device reliably, though doesn't get picked up by syslog -w or get received by the ASL config redirect: syslog -s -l error -k Message "appName: this is a test2" syslog -s -l notice -k Message "appName: this is a test3" ASL configuration, which is loaded according to syslog -config: > /var/log/appName/appName.log mode=0640 compress format=std rotate=seq file_max=50M all_max=500M ? [CA= Sender appName] file /var/log/appName/appName.log My end goal is really to get just a working python logging -> var/log/appname/appname.log again so glad to just be pointed in the right direction if way off base. -- Philip Bloom Director, Services Engineering *AppLovin Corporation* M: (786)-338-1439 <786-338-1439> [image: LinkedIn] <https://www.linkedin.com/company/applovin> [image: Twitter] <https://twitter.com/AppLovin> [image: Facebook] <https://facebook.com/AppLovin> [image: Instagram] <https://www.instagram.com/applovin/> [image: AppLovin] <https://www.applovin.com/>

Timezone for datetime.date objects
by Morten W. Petersen March 6, 2022

March 6, 2022

Hi. I'm working on a project where I need to query data for a given year, in the correct timezone. For accounting purposes. The code I worked on today is here, see also the version history: https://github.com/morphex/ethereum-classic-taxman/blob/main/generate_csv.py I was initially using the date object to get the right timespan, but then found that using the right timezone with that was a bit of a pain. So I went for the datetime object instead, specifying 0 on hour, minute and second. What's the thinking behind this with the date object? Wouldn't it be nice to be able to specify a timezone?
