[Python-ideas] Python with braces formal proposal?

Hello, There're tons of projects which introduce alternative braces (i.e. C-like) syntax for Python. Most of them are however not properly documented, and definitely not spec'ed for what they do. I wonder, does anyone here remember more or less formal proposal for braces syntax? A "minimum viable

[Python-ideas] Re: Add venv activate command to the venv modules

To get around the fact that activating a virtualenv requires setting environment variables in the current shell poetry has a shell command that simply spawns a new shell with the appropriate environment variables: https://python-poetry.org/docs/cli/#shell So a cross-platform `activate` command

[Python-ideas] Re: Add venv activate command to the venv modules

Unfortunately, that wouldn't work. Activating a virtual environment means setting some env vars in the current shell, and Python is fundamentally unable to do that - it can only be done within the shell itself (by sourcing a script). You can, of course, simply run the Python executable from that v

[Python-ideas] Re: Add venv activate command to the venv modules

I know nothing of the details, but I think the goal is to have the same command work (almost) everywhere, yes? That does not need to be a python script, however. In fact, it's nice if activating an environment is as fast as possible so firing up Python to do it is less than ideal. Anyway -- I'd e

@Christopher Barker You nailed it! I've used the conda activate command many times. It should in theory be possible in Python @Chris Angelico Yes mere shell commands passing via Py does not work, maybe a file way with results in current shell as @M.-A. Lemburg points out, venv already genera

For me it easier to do with C++, I know C, but with C++ it is more maintainable and easier to add new feature and also easier to refactor ... I am not sure if CPython maintainers team will appropriate that I add C++ in code base ... But I can try, I will try to find time to create small proof o
