I think the whole use of the language displays as in
6.2.4. Displays for lists, sets and dictionaries
For constructing a list, a set or a dictionary Python provides
special syntax called “displays”, each of them in two flavors:
either the container contents are listed explicitly, or
they are computed via a set of looping and filtering instructions,
called a comprehension.
is very odd. I don't know anybody who talks of 'displays'. They
talk of 'two ways to construct a'.
Who came up with the word 'display' and what does it have going for
it that I have missed? Right now I think its chief virtue is that
it is a meaningless noun. (But not meaningless enough, as I
associate displays with output, not construction).
I think that
6.2.4 Constructing lists, sets and dictionaries
would be a much more useful title, and
6.2.4 Constructing lists, sets and dictionaries -- explicitly or through
the use of comprehensions
an even better one.
Am I missing something important about the 'display' language?
Laura
