Okay, I've made some progress. Turns out, I was erroneously assumed I was
in an IPython shell because it had 'magics', but it was just the idle
interpreter, (never spent much time in Idle). All it took was creating a
new shell config, and ticking the IPython box.
I'm going paste in some of the shell interaction with comments interspersed
and a question.
Python 3.7.7 (default, Apr 15 2020, 05:09:04) on Windows (64 bits).
This is the Pyzo interpreter with integrated event loop for PYQT5.
Using IPython 7.13.0 -- An enhanced Interactive Python.

%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.

Interactive namespace is empty.

Qt WebEngine seems to be initialized from a plugin. Please set
Qt::AA_ShareOpenGLContexts
using QCoreApplication::setAttribute before constructing QGuiApplication.
Leo 6.3-devel, devel branch, build cbb73524c3
2020-04-15 04:24:37 -0500
Note on using QApplication.exec_():
The GUI event loop is already running in the pyzo kernel, and exec_()
does not block. In most cases your app should run fine without the need
for modifications. For clarity, this is what the pyzo kernel does:
- Prevent deletion of objects in the local scope of functions leading to
exec_()
- Prevent system exit right after the exec_() call

Hmm, 'g' is not availible, let's try a fully qualified name, reaching down

question,what should I use for my argument?

The question is at In [5] above, I guess it would be 'g.app', but 'g' isn't
available, any suggestions?
Doing things like this is the reason I first started looking at IPython, to
provide a way to explore Leo code.
