Application Distribution using Embeddable Zip on Windows
I am developing a parser with PLY and was hoping to distribute it to users. Ofcourse there're plenty of Ways to build a executable of an Python script such as PyInstaller , Py2Exe and some others, but they have their problems , one of them which is their output distribution size is huge, a simple "hello world" program would even cost user 30 to 50+ megabytes of storage. Distributing on Linux is not that much of hassle with snap packages or even Appimages. But on windows it's a mess. But Python Embeddable Zip seems promising to me, it's very lightweight. But the thing is I couldn't figure out how to build a "launcher" (As mentioned here -> https://docs.python.org/3/using/windows.html) for my application? Any help or suggestions would be very much appreciated. ~Palash Bauri -- https://mail.python.org/mailman/listinfo/python-list

Putting a Python interpreter onto the users' systems is the job of python.org and/or the Windows app store. You should just have to worry about your own app. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
Re: Application Distribution using Embeddable Zip on Windows
Well , in some cases that is true, but in my program's case that's not true as it's targetting not-so-much tech savvy users. I would like to make an compact plug-and-play solution. And , I think using Python Embeddable zip and a custom launcher will be more suitable for my program.

Re: Application Distribution using Embeddable Zip on Windows
Well, that crossed my mind earlier, but as my program is a text parser and has it's own input & output source filetype, it should have those filetypes associated with the program. Just using an MSI installer will not do that trick. ~Palash Bauri On Wed, 17 Jun 2020, 7:18 pm Shakil Khan, wrote: > How about writing a windows MSI installer and wrapping Python and your > script together in the MSI. > > $hakil > > > On Jun 17, 2020, at 6:44 AM, Palash Bauri > wrote: > > > > Well , in some cases that is true, but in my program's case that's not > > true as it's targetting not-so-much tech savvy users.

Re: Application Distribution using Embeddable Zip on Windows
Well , I didn't know that single scripts can be used to associate filetypes. I will test it out. Currently I'm doing an experiment with Embeddable distribution , Writing a launcher with rust. I have no idea what's the efficient or correct way to do it. Let's hope for the best. I think they should've explained how to write an Launcher or even an example code in the docs. I will have your solution as an backup option. ~Palash Bauri On Wed, 17 Jun 2020, 8:30 pm Shakil Khan, wrote: > May be I have not understood your requirement. > But let me put what I understood and how can it be achieved. > > Requirement:- > There is a file in system called as abc.pal, this file when double > clicked produces a file called as abc.parsed > > Solution: > 1) Pack the MSI and Python Binary in MSI > 2) Unpack and install the MSI and as part of it install the Python in > standard Path and update the PATH > 3) Associate the file type *.pal to open with your application say > Palash_parser.py > 4) When the file abc.pal is double-clicked the associated application is > Palash_parser.py. > The application Palash_parser.py can run without any issues as the Python > is already installed and in Path and produces abc.parsed > > Sorry if this is not what you intended. > Good luck then. > > $hakil > > On Jun 17, 2020, at 7:48 AM, Palash Bauri wrote: > > Well, that crossed my mind earlier, but as my program is a text parser and > has it's own input & output source filetype, it should have those filetypes > associated with the program.

Property for dataclass field with default value
Hello All, I have some trouble using @dataclass together with @property decorator or property() function. >From the documentation and PEP is seems that the intended behaviour of @dataclass is to be the same as normal __init__() that sets instance variables. But it seems that when using @property decorator some parts work differently when relying on default values. I'm using Pyhton 3.8.3 for this. Using the code: from dataclasses import dataclass @dataclass class Container: x: int = 30 @property def x(self) -> int: return self._x @x.setter def x(self, z: int): if z > 1: self._x = z else: raise ValueError c= Container(x=10) print(c) c= Container() print(c) output is: Container(x=10) Traceback (most recent call last): File "/Users/ivanivanyuk/Documents/Shared/repos/bitbucket/evbox/g5plus-automated-testing/dataclass_example.py", line 18, in c= Container() File "", line 3, in __init__ File "/Users/ivanivanyuk/Documents/Shared/repos/bitbucket/evbox/g5plus-automated-testing/dataclass_example.py", line 13, in x if z > 1: TypeError: '>' not supported between instances of 'property' and 'int' Code with __init__() being inserted that should be roughly the same as generated by the @dataclass decorator: @dataclass class Container: x: int = 30 def __init__(self, x:int = 30): self.x = x @property def x(self) -> int: return self._x @x.setter def x(self, z: int): if z > 1: self._x = z else: raise ValueError c= Container(x=10) print(c) c= Container() print(c) output is: Container(x=10) Container(x=30) As far as I can see, this happens because actual __init__() generated by the @dataclass decorator looks like: def __init__(self, x:int = ): self.x = x I came up with a really convoluted way to work around it (just for fun, as this clearly defies the idea of dataclasses as a way to decrease boilerplate code): from dataclasses import dataclass, field def set_property(): Container.x = property(Container.get_x, Container.set_x) return 30 @dataclass class Container: x: int = field(default_factory=set_property) def get_x(self) -> int: return self._x def set_x(self, z: int): if z > 1: self._x = z else: raise ValueError c= Container(x=10) print(c) c= Container() print(c) output is: Container(x=10) Container(x=30) So, what I'm missing here? Is there some way to use field() or decorators to make property just work the same as in non-decorated class? Best regards, Ivan Ivanyuk -- https://mail.python.org/mailman/listinfo/python-list
Problems with python383.dll
Dear Sirs, I tried to install the software Python 3.8.3 (32 bit), but after it finished and I tried to start it, there appeared a message in which it was written that it couldn't find the file python383.dll and stopped. What can I do? Do you have this file so that I can insert it manually. I thank you for your help. Best wishes, Manuel Fernandez -- -- https://mail.python.org/mailman/listinfo/python-list

Re: uninstallation issue
Before you uninstall right click on idle and find the location where python is installed. Probably it would be under C:\\Programe files\\python. And then uninstall python. After that you will see that some folders where deleted but others where not. Delete the others and you will have uninstalled python.

Where did you download the installer from? How did you try to start it? Normally python is a command-line tool, so you run it from a command prompt, not from the start menu.
