Slight syntax difference breaks example.py on the Pico W

[joewez]

The example.py file does not run correctly on a Pico W because the sys.implementation function returns _mpy which does not match the current value being returned... mpy. Not sure how this should be handled.

Not sure it is a Nanoweb related problem.

Could you send an example ?

As an absolute novice in this area I can't contribute any more than the fact that today I have also been trying to run the example on Pico W and I'm also seeing 'mpy' errors, e.g.:
Task exception wasn't retrieved
future: coro= <generator object 'handle' at 20025020>
Traceback (most recent call last):

The current implementation of MicroPython on the Pico W seems to expect _mpy instead of mpy in the sys.* library, as per the MicroPython docs

Change "sys.implementation.mpy" to "sys.implementation._mpy" on line 73 of example.py and it all works fine for me on the Pico W without exceptions, and displays and updates the system info as it should.
