I would like to propose an enhancement in code editor.
When you hover mouse on a variable, a tooltip is popped-up with message: "This is a (string/integer/list/bool/..etc)".

It is interesting for me and the team that I work with, that the value of the variable is popped-up(if it is already on variable explorer). Otherwise, continue to show "This is a ....." message.
The reason it that when we are debugging a code, it is not so efficient to look for variables in variable explorer or type it in IPython console.

Therefore, I propose something like this bellow:

I made an initial version of this changing codeeditor.py, class CodeEditor, method _handle_hove as follows:

            text = self.get_word_at(pos)
            value = None
            if text:
                try:
                    main = self.window()
                    shell = main.ipyconsole.get_current_shellwidget()
                    if shell:
                        value = shell.get_value(text)
                        if value is not None:
                            from qtpy.QtWidgets import QToolTip
                            QToolTip.showText(
                                self.mapToGlobal(pos),
                                f"{text} = {repr(value)}"
                            )
                            return
                except Exception:
                    pass

I hope I can implement this enhancement with you approval. Thanks in advance.
