It just seems that versions are usually released on schedule so I'm wondering if there's some problem. > Was an update today in python-dev (there are still release blockers) For the record: https://groups.google.com/g/dev-python/c/_S8YGysqsxc This does seem an unusually long delay. In any event, it's clearly better to make sure it's working properly than to rush to keep to some schedule.

I am at the pre planning stages of making a Rust implementation of the Python virtual machine and to avoid ambiguity I've been working with Rython as the name. I tried looking for a Monty Python themed name but the good ones seem to be taken. Otherwise as for a timeline, solo I figure it's going to take me a couple years to get something that actually passes cpython's python unit-tests.

RTF documents are not simple text documents (https://en.wikipedia.org/wiki/Rich_Text_Format) so if you want to extract the text contained in these documents you will need to use a library that can do this (eg: https://pypi.org/project/striprtf/) ...or write a parser yourself.

3.11.0b4?
by Richard David June 23, 2022

June 23, 2022

Is there a new scheduled date for releasing 3.11.0b4? Are there issues with b4 that have implications for b3? I realize it will be released when ready and am not trying to push or harass anyone involved. It just seems that versions are usually released on schedule so I'm wondering if there's some problem.

But my point is to justify why I want months. And it depends on the application. Let's suppose a program for Joe User to clean something - files, for example. There are no rules except for the comfort of the user. He would prefer to be able to say 9 months back instead of 270 days. And by 9 months, he expects to count down 9 months. Not 270 days. That's what happens with the script I am writing. Paulo
