Re: How Do I Get A Bug In Multiprocessing Fixed?
Hi Michael It may be helpful to populate the ticket with further details: * actual output from when you execute the server and client (possibly with extra verbosity enabled) * system you are running this on (windows, macos, linux) flavour / version details * minor version of Python interpreter used * whether you are using a packaged version from your os distributor or from python.org (or even built your own) * If you believe it's a regression the version it is working on Some more guidance can be found here covering some of the above https://docs.python.org/3/bugs.html I am very interested to note that a report filed in February hasn't had at least one person take a brief look at it and post a note or set a status like "needs more info" etc. Also I am by no means an expert in multi processing at all as so far my webapps work worker processes, I am wondering if the wrong approach to this may be happening and so the client is trying to reuse the same pipe and it may need a different tear down / process to release that and create a new pipe / socket / underlying connection cleanly rather than the re connect in the same object. For example I am running python 3.7.7 on windows: Manager Output: >python manager.py In test_method >python manager.py Client Output: result: ', TEST' Kill and restart the server and press return Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting Got exception , ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None) Reconnecting # At this point I terminated the manager Got exception , ConnectionRefusedError(10061, 'No connection could be made because the target machine actively refused it', None, 10061, None) Reconnecting Traceback (most recent call last): File "C:\Users\Alexander\AppData\Local\Programs\Python\Python37\lib\multiprocessing\connection.py", line 619, in SocketClient s.connect(address) ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it During handling of the above exception, another exception occurred: Traceback (most recent call last): File "client.py", line 27, in manager.connect() File "C:\Users\Alexander\AppData\Local\Programs\Python\Python37\lib\multiprocessing\managers.py", line 532, in connect conn = Client(self._address, authkey=self._authkey) File "C:\Users\Alexander\AppData\Local\Programs\Python\Python37\lib\multiprocessing\connection.py", line 492, in Client c = SocketClient(address) File "C:\Users\Alexander\AppData\Local\Programs\Python\Python37\lib\multiprocessing\connection.py", line 619, in SocketClient s.connect(address) KeyboardInterrupt Regards Alexander Alexander Neilson Neilson Productions Limited alexan...@neilson.net.nz 021 329 681 022 456 2326 On Fri, 18 Jun 2021 at 15:27, Michael Boom wrote: > The below issue is pretty serious and it is preventing me from using a > system I wrote on a larger scale.

Re: Pycharm Won't Do Long Underscore
Hi Tony The “long underscore” (often called Dunder as “double underscore”) is actually two underscores as you are seeing shown in PyCharm. However the display of it as one long underscore is a ligature (special font display to communicate clearer) and to enable these in PyCharm go to the settings dialog (depending on windows or Mac this could be in different locations) and select Editor > Font In that screen select “enable font ligatures” and if your font supports it (like the default JetBrains Mono does) that will start to display the double underscores as a single long underscore.

Re: Pycharm Won't Do Long Underscore
Hi Tony Absolutely. The “long underscore” is just a display thing. Underneath it is always two underscores. The only difference is what your editor is showing (or how the underscore is drawn in the display font - as some fonts make the underscore the full width or slightly over the edge of where the character will be displayed so that many underscores look all joined up like a line) These links may provide you with some useful reading around this and what underscores signal in Python. https://dbader.org/blog/meaning-of-underscores-in-python https://dbader.org/blog/python-dunder-methods Happy to have helped and good luck with your Python journey.

Re: strip() method makes me confused
Because the strip methods argument is the set of characters to remove from
either end. So it checks from the ends character by character until it finds a
character that isn’t in the set. Then it removes everything prior to that (or
after that at end of the string) and then returns the result.
So your first example leaves “banana” as the string because all characters
after and before that string in the original string were found in the set.
However in your second example the set only contains the comma and the string
neither begins nor ends with commas so if (first character) in (set containing
comma) returns false so it stops searching from that end and does the same at
the other end.

Hope that helps.

Re: Python 3.8 or later on Debian?
Python 3.7 is part of Buster (Debian old old stable) If you moved to Debian bullseye you would get offered 3.9 (old stable) Currently the stable version (Bookworm) would give you 3.11 I am not aware of anyone maintaining a repo for old Debian versions to get newer Python versions. But I know in the past I did build newer Python versions (mostly on raspberry pi’s) Regards Alexander Alexander Neilson Neilson Productions Limited 021 329 681 alexan...@neilson.net.nz > On 19 Sep 2024, at 10:42, Ulrich Goebel via Python-list > wrote: > > Hi, > > Debian Linux seems to love Python 3.7 - that is shown by apt-get list, and > it's installed on my Debian Server. > > But I need at least Python 3.8 > > Is there a repository which I can give to apt to get Python 3.8 or later? > > Or do I really have to install and compile these versions manually?
