Specifically for programming, yes, and Python is among the supported
languages - but according to their web page, they support many
languages (and in many other languages, whitespace is either not
meaningful, or else you might actually want the Tab key to produce a
tab character.)
Anyway, I'm only guessing that the reason your indentation was
disappearing was a tab/space issue; I don't actually know.
