Autocompletions for file paths in Notebooks

[tanhakabir]

When you open a new blank notebook, you're able to run cells immediately but when you need to import in data like a csv from a local file it's confusing to know that you're in a buffer and not the file system yet. And so it's confusing to know which directory you're in to make the path from.

A simpler solution could be to force the user to save the Notebook somewhere before attempting to run the cell but I'm not sure if that's a better experience.

If you want to know which directory you're in, you can use os.getcwd() or os.path.abspath('').

right! but I was wondering if we could have autocompletions so it's easier to debug for those aren't aware of that function

In that case you would need to have the language server know that you're wanting a file path (which is hard with so many APIs taking a string as a file path). I also don't know how the trigger would work for completions since you don't want every string to be considered a file path.

But ultimately this would be an ask for Pylance, so I'm transferring this to them.

Trying to find our past conversation about this and failing; this seems like something that Jupyter should already be providing as a part of its completions, as they use the Jupyter + Pylance to build their list, and I think they do path completion. We don't use discussions to track enhancements, so a new issue would be warranted if I can't find our last conversation.
