I have a stylistic question. In most languages words in var. name are
separated by underscores or cap letters, resulting in var names like
var_name, VarName and varName. I don't like that very much because all
3 ways of naming look bad and/or hard to type. From what I understand,
scheme can have variables like var-name. I'm curious about reasons
that python chose to disallow this.
Because we'd prefer var-name to mean subtraction of values: var minus
name. If you want to use a that character in names, what syntax would
you prefer for subtraction? Do you consider lisp/scheme (- a b) to be
reasonable in Python?
Another question I have is what
other languages allow this naming scheme? Were there any languages
that allowed space as a separator?
Fortran used to. (Haven't checked in on it in years though so I don't
know now). And it not so much as allowed spaces as it *ignored* all
spaces. This was now-a-days considered a *really* bad idea, and is
rumored to be responsible for a bug that crashed a satellite. (At least
that's the way a nice urban legend tells it.)
What would be a practical way to
separate variables from keywords in that case? "some long variable
name", 'just a string', or maybe using 2 spaces: one var + other
var + third var ? I think being able to easy have very long names
for vars that are easy to type would be a fairly significant
advantage. I know I'm probably being too obsessive about this but
that didn't stop me from posting. Comments?
