Horrible abuse of __init_subclass__, or elegant hack?

The Python 'education' is offered at a lower density than the
explanations of slang in variants of ?the? English-language...

The Cartesian coordinate system, as used in geometry, mapping, etc, was
named after the French philosopher René Descartes.

Possibly Descartes' most famous quotation is "je pense, donc je suis",
which some reason (best known to others) we were taught in Latin, as
"cogito, ergo sum". Most will be familiar with the English translation,
"I think, therefore I am".

A[n] horse-drawn (pulled) vehicle might be a cART, and cARTESIAN water
comes from an underground supply or aquifer.


Whilst we are 'messing around' with [human] languages, my French
vocabulary/translation capability has been extended by discovering that
"artesian" is "artois". Artois was a kingdom/principality that is part
of modern France, 'up' by the Belgian border. A man with French
heritage, but purported to be Dutch, built a brewery in Belgium. Hence
today one of that country's most famous exports is "Stella Artois" beer
("stella" meaning "star"!).

(but this isn't teaching me much Python - or OpenCV: this weekend's
objective...)

My anxiety over 'ordering' comes to the fore: if there are multiple
inputs and/or multiple outputs, how can one tell where the former series
ends and the latter begins?

"Explicit" cf "implicit"?

Cadbury do not make chocolate!
Neither do Hershey, for that matter!
There, now that I've upset most of the English-speaking world...

PS they use the milk to 'water down' the chocolate! It's much like
buying Easter Eggs: the density of chocolate is much lower for the price.

Time for another language lesson?

"tucker" is Australian slang for food. Hence "tucker-bag", the
'waltzer's' equivalent of a lunch-box or tiffin tin.

Back when Australia was re-considering their choice for National Anthem,
I was in full expectation (and great hope) that they would select
"Waltzing Matilda". Sadly, they did not (instead: "Advance Australia
Fair").

However, within one poem/song it is possible to learn a considerable
number of (100-year old) Australian slang terms...

Whilst visiting Freemantle (Western Australia), as a guest of Royal
Australian Navy Vets, we were marched-away from the Remembrance Day
Parade to the tune of Waltzing Matilda - something of an highlight (for
me at least)!


Contrarily "tuck" in (old) English slang represented "sweets" (or
"lollies", "candy", etc, in other forms of English). Some say it had
wider application, but I don't recall it ever being used more generally
as "food" or "meal". That said, "tuck in" is certainly slang for 'start
eating [your meal]'.

However, the phrase "best bib and tucker" means "Sunday best" clothing
or 'dressing for dinner. Those who are still following-along in the hope
of a Python reference may like to contemplate the similar implications
carried by "The Monty Python Matching Tie and Handkerchief".

>From "tuck" we get "tuck shop" (which Wikipedia tells us is indeed
closely-related to schools and confectionery
(https://en.wikipedia.org/wiki/Tuck_shop)!).

With that understanding(?) or allusion you may feel equipped to realise
the specialty nature of the "cheese shop", and thus the
Monty-Pythonesque previous name for PyPi!

Toodle-pip!
