My question is why, and where do I find a reliable source of information
on formatting numbers? Not interested in replacement values like '{}
{}'.format(1, 2).
Agreed: there's ton(ne)s of information 'out there', much of it old, eg
Python2, "formatter" (deprecated since v3.4), methods pre-dating
f-strings, etc; and more of it rather casually thrown-out-there.
Learning from StackOverflow (etc) has its limits/perils!
Authoritative Python docs: https://docs.python.org/3/
The "Mini-Language":
https://docs.python.org/3/library/string.html#formatspec
Current advice (v3.6+) is to study the newer f-strings (formally
"formatted string literals"):
https://docs.python.org/3/tutorial/inputoutput.html which came from PEP
498: https://www.python.org/dev/peps/pep-0498/
