The preferred and simplest way to do this would be

    context = py.ssl.create_default_context()

To summarize, there is no need to import anything, just call the fully
qualified py.library.function name.

Btw, the `python_cmd` function is part of the Symbolic package and is
completely unrelated to the Pythonic package (for now).

If you _really_ want to use pyeval and pyexec, this also works

    pyexec('import ssl')
    pyexec('context = ssl.create_default_context()')

or this

    pyexec('import ssl')
    context = pyeval('ssl.create_default_context()')

But I would much prefer people use the fully transparent and Matlab
compatible syntax `context = py.ssl.create_default_context()`.



 On the IRC a person asked if we could send an email from inside of octave. Matlab has a function sendmail.
So I thought about doing it from python. this next code works in python and you can do:
system('python')  and this works from inside octave

Then I tried to use pyexec  and do it from inside of octave.
This is how far I have gotten  --  I cant get the last 3 lines of to work.
any help would be good.
