Feature request - Implement python auto-complete

I'll take a stab at it when I get the chance (but it may be a little while)

Good idea, I would also like autocompletion in Starboard Notebooks. It seems pyodide already has done some work for autocompleting things that exist in the Python globals(): https://pyodide.org/en/stable/usage/api/python-api.html?highlight=complete#pyodide.console.Console.complete

Some quick results could probably be achieved by feeding the current code block up untill the location of the cursor to this method, and display the results in a suggestion box.

The javascript scope should contain a proxy to the pyodide module under the alias pyodide_py: https://pyodide.org/en/stable/usage/api/js-api.html?highlight=pyodide_py#pyodide.pyodide_py

Same for me. I would like to make a first version of autocompletion, but let's avoid doing double work.

For full autocompletion, we could look at how IPython does this: https://ipython.readthedocs.io/en/stable/config/integrating.html#tab-completion

We could merge the results of Console.complete with the results from calling __dir__ on objects.

This could be extended by using IPython's _ipython_key_completion_ if the cursor is in a place where it's indexing a Python object (within square brackets).
