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 two also seem to be writing about different things when you write > "THE locale".

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.
