Likely? Very much so, to the extent that it is, if not a FAQ,
certainly a Not All That Uncommonly Asked Question. So many times
someone places logging code in something that gets called twice, and
ends up with two handlers. Personally, I much prefer to debug with
straight-up 'print' - much less hassle. I'd turn to the logging module
only if I actually need its functionality (logging to some place other
than the console, or leaving the log statements in and {en|dis}abling
them at run-time).
