Re: Configuring WiFi from OSX

The Raspberry Pi Foundation documentation for setting up WiFi with Raspbian is here: https://www.raspberrypi.org/documentation/configuration/wireless/README.md The section about a 'headless' configuration may be relevant. If you need further clarification, look for one of the many reposts by forum u...

Re: RaspberryPi 3 B +: random reboots caused by "beefy" power supply

Any idea what could it be?

From your description, one possible explanation is that your anonymous 2.1amp Power Supplies (and/or their associated cables) may in practice not be capable of delivering a stable voltage at times of peak current demand.

Re: apt-get dist-upgrade vs flash with new version of OS

Welcome to the Raspberry Pi forums. If one had a fresh install of Raspian Jessie and ran apt-get dist-upgrade is that roughly equivalent to wiping the SD card and flashing a recent image of Raspian Stretch? No. Not even 'roughly'. The former leaves you with a Raspbian Jessie Operating System, clearl...

If a library import was well-commented source code rather than compiled code, the steps needed to view what is under the hood would be simply to open the library file for reading.

No.

But one (actually two) thing you could check, as it isn't obvious from what you have posted, is that /home/pi/PythonTest/app2.py is executable and that it begins with a 'shebang' line that will cause it to be run by the Python2 interpreter.
