My question is why, and where do I find a reliable source of

I suspect the thing you were overlooking was that format() expects to be
given a format specification, and you gave it a format string. Instead
of format(num, "{0:.1f}"), you wanted format(num, ".1f"). If you had
tried "{0:.1f}".format(num) instead, you would have found that worked too.
Thanks Rhodri
