Hi,

Switching to lxml for xml parsing and generating, I was somewhat puzzeled by
the usage line's like
XHTML_NAMESPACE = "http://www.w3.org/1999/xhtml";
XHTML = "{%s}" % XHTML_NAMESPACE
With more modern f-string's this could also be written as
XHTML = f"{{{XHTML_NAMESPACE}}}"
This may be because I only started on Python on 3.7, and have never worked with
any 2.x
I quite understand there is no time to rework all the doc's in the low income
on this project. Just two questions:
- is there (another) good reason not to is f-string formatting? And if not
- is there a way to assist on reworking the doc's
It's reasonable to update the docs to Py3 style by now, and a bit of that
has already been done. The question is whether
XHTML = f"{{{XHTML_NAMESPACE}}}"
is really more readable than
XHTML = "{%s}" % XHTML_NAMESPACE
given the amount of curly braces with different meanings that a reader has
to go through. To me, personally, the second seems quicker and more obvious
to read, whereas it takes me a while to understand what the equivalent
f-string does.
I think this is a case where we should keep the (IMHO) simpler non-f-string
variant.
