Feature: Completion Suggestions for Dictionary Keys

[KeithScheiwiller]

One feature I've found useful in Chrome's devtools is that it will offer completions for Object keys even when accessed with the someObject[key] syntax. I figure something similar could be possible for ptpython as well, at least for "vanilla" Python dictionaries.

For example, if I have the dictionary
my_dict = { "foo": 42, "bar": 24, "food": "pizza" }
when typing
my_dict["fo into ptpython it could offer to complete to my_dict["foo"] or my_dict["food"].

Hopefully this is something that would play will with Jedi, etc.!

Hi @KeithScheiwiller,

This would be a nice feature indeed, but that's probably something for the Jedi project. Can you open an issue on their repository if you're still interested?

If they don't do this, then we can probably add a second completer that does exactly this for very simple cases (when the dictionary itself is directly in the global scope).

Oh ya, good point! I'll open up something there.
Thanks!
