Yes indeed. Python 2.7 in the Debian 3.8.13 bone50 on my BBB does flag the
error, telling me that *w* is not correct.
I'm not sure as I haven't gone back to my old code to try it again, but I
suspect my use of Try/Except sort of hid the error, just telling me that
the Try failed and not telling me exactly what the error was and I simply
assumed the error was in the name or path in the open command. Clearly I
should have just used the open command outside of the Try/Except and then
an error message would have popped up telling me that the *w *was
incorrect. Hopefully I have learned from this, first to double-check the
syntax and second to dig a little to find out why the open command (or
other command) didn't work. I continue to be embarrassed at this dumb
mistake but I am going on to probably make other mistakes. However, my code
is working perfectly, GUI and all, including writing a logfile to the eMMC.
Thanks for everyone's help. I certainly needed it.
