We have been supplying many possible reasons or consequences for why the
implementation of python does not do what the OP wants and even DEMANDS.
I am satisfied with knowing it was because they CHOSE NOT TO in some places
and maybe not in others. It is nice to see some possible reasons, but

Many "warnings" can safely be ignored.
The function as shown does not look right. I assume it is just an example, but
a function that ignores the argument supplied is already a tad suspect.
Since it is SUGGESTED that the variable name "self" normally is used in a

Good example, Rob, of how some people make what I consider RELIGIOUS edicts
that one can easily violate if one wishes and it makes lots of sense in your
example.
Let me extend that. The goal was to store a character string consisting of
multiple lines when printed that are all left-aligned.
Rob,
There are lots of nifty features each of us might like and insist make much
more sense than what others say they want.
Sometimes the answer is to not satisfy most of those demands but provide
TOOLS they can use to do things for themselves.
As you agree, many of us have found all kinds of
Rob,
It depends. Some purists say python abhors one liners. Well, I politely
disagree and I enjoyed this book which shows how to write some quite compressed
one-liners or nearly so.

Grant,
I am not sure it is fair to blame JSON for a design choice.
Use of commas can be done many ways in many contexts.
One context is a sort of placeholder. Can you have a language where a
function has multiple arguments and you can skip some as in:
Func(a,b,c)
Func(a, b,)
Func(a,,)
Or

FWIW, gmane is still there, and still working fine. I read this list

That is a good idea.
Even more so when the items are on separate lines:

"spam",
"eggs",
"cheese",
]

That is a reasonable use, Rob, albeit I would refactor that example in quite a
few ways so the need for a semicolon disappears even for lining things up.
So to extrapolate, perhaps a related example might be as simple as wanting to
initialialize multiple variables together might suffice as

How did you know that was the method I used to indicate I had properly
