Once you open the Locale can of worms, EVERYTHING has a locale, to say you
aren't using a locale is to say you are writing something unintelligible, as
you can thing of the locale as the set of rules to interpret

Python, like many languages, define the formatting of things, so Python
programs should be interpreted according to the "Python" locale (which may
actually be named "C").

You have THE locale for a given piece of data. My point is that Python has
adopted the C method of a single global locale for a program, so in the program
 there is a 'THE Locale' which may actually need to be different when
processing different information, leading to some of the issues.
