I'm not sure what you're asking. Why did it print 44.1°F six times? If so, this is exactly what Gary and I were discussing earlier: your extension gets loaded once *for each template*. So, that's six calls to get_extension_list() and six prints of 44.1°F.
How often the extension gets used in the template is an entirely different matter. For example, if you take out your line stats.day().outTemp.last, but put a print statement in, say, TimespanBinder.__getattr__, nothing will get printed unless the tag appears in your template. Does that help? -tk On Fri, Jun 30, 2017 at 5:38 PM, Thomas Carlin <[email protected]> wrote: > Okay, so I distilled the code down to the bare minimum, and still get the > same results, (returning N/A the first time it runs for each report cycle), > and have included it below.
