It depends on context and audience. If you're talking about Python code
with other relatively experienced Pythonistas, no I don't think it's
wrong. When you're talking about Python versus other languages where
"variable" corresponds with "a possibly typed memory location", or
you're talking with someone who is coming from such a language, then
it's probably best to talk about names and objects. Such pedantry is
useful in the latter cases but not so much in the former.
