I'm not sure how that differs from a .shiv directory, which is not global.
But a way to share packages in the "central place for packages" would be
nice. -- maybe how conda does it with hard links?

So what for the Request is used for then?
In general when you see that something in Python starts with a capital
letter, that indicates a class. Check out the relevant section of the PEP8
coding
In the code you linked, I don't see where the *R*equest is used. The
request variable is setup by flask when you annotate the function with the
resource endpoint and POST method. It contains the content of the request
which can be converted to json if that content type was specified.

Nope. Only displays the board on the console. An early version had the

My approach is to ensure flake8 (a combination of pyflakes and pep8

I routinely get 10/10 for my code. While pylint isn't perfect and
idiosyncratic at times, it's a useful tool to help break bad programming
habits. Since I came from a Java background

Below is the code that I mentioned in an earlier thread.

That works fine and dandy. Except Pylint doesn't like it. According to

You're thinking of the whole "string", but you're operating on

Because the two-pronged test, a) if all cased characters are lowercase

Greetings,
I was playing around with a piece of code to remove lowercase letters
and leave behind uppercase letters from a string when I got unexpected
results.
string = 'Whiskey Tango Foxtrot'
