Here's what I do:

def getheightwidth():
    """ getwidth() -> (int, int)

    Return the height and width of the console in characters """
    try:
        return int(os.environ["LINES"]), int(os.environ["COLUMNS"])
    except KeyError:
        height, width = struct.unpack(
            "hhhh", ioctl(0, TIOCGWINSZ ,"\000"*8))[0:2]
        if not height: return 25, 80
        return height, width

Where TIOCGWINSZ lives is an interesting game across Python versions.
It's in termios now.

I should probably look at terminfo too, but that would be the last
check.

I think ncurses' own order of checking goes:

env vars
ioctl
terminfo
25x80

but I haven't looked at this for a while.
