[issue41274] Better way to random.seed()?
New submission from Juan Jimenez : I have invented a new way to seed the random number generator with about as random a source of seeds as can be found: hashes generated from high cadence, high resolution images of the surface of the Sun. These are captured by the Solar Dynamics Observatory's (SDO) Atmospheric Imaging Assembly's (AIA) cameras at various frequencies. I wrote the POC code in Python and can be seen at https://github.com/flybd5/heliorandom. The HelioViewer project liked the idea and modified their API to do essentially what my POC code does at https://api.helioviewer.org/?action=getRandomSeed. Perhaps a solarseed() call could be created for the library to get seeds that way rather than from the system clock? -- components: Library (Lib) messages: 373487 nosy: flybd5 priority: normal severity: normal status: open title: Better way to random.seed()? type: enhancement versions: Python 3.10 ___ Python tracker <https://bugs.python.org/issue41274> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Juan Jimenez added the comment: I'm not a Python guru, but I was wondering, is it possible to write a new module that overrides the seed() method in the random library in its initialization code and replaces it with this method of seeding the generator? -- ___ Python tracker <https://bugs.python.org/issue41274> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Juan Jimenez added the comment: How would I know if my demo is good enough to be included in that repo? Is there a guide for this, or do I just create a pull request, throw it over the fence and wait until the wolves either grunt in approval or throw it back at me in pieces? I ask because I have never participated in a repo related to as big a project as Python 3. :) -- ___ Python tracker <https://bugs.python.org/issue41274> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue41446] New demo, using a web api
New submission from Juan Jimenez : As per a suggestion in https://bugs.python.org/issue41274 I would like to submit for consideration a new demo program, one that demonstrates how to use a web API to generate a pseudo-random generator seed from high resolution, high cadence images of the sun. I will be submitting a pull request for consideration. -- components: Demos and Tools messages: 374620 nosy: flybd5 priority: normal severity: normal status: open title: New demo, using a web api type: enhancement versions: Python 3.10 ___ Python tracker <https://bugs.python.org/issue41446> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue25058] Right square bracket argparse metavar
New submission from Juan Jimenez-Anca: When trying to assign the metavar in add_argument() method of argparse module I'm unable to include characters after a right square bracket.
