Short without being too unreadable:

def conv(x, sep='.'):
    x = str(x)[::-1]
    return sep.join(x[i:i + 3] for i in range(0, len(x), 3))[::-1]

Or more simple-mindedly...

def conv(x, sep='.'):
    x, y = str(x), []
    while x:
        y.append(x[-3:])
        x = x[:-3]
    return sep.join(reversed(y))
