You don't need javascript, in this case, assuming the reference is to the
UK lotto --  A simple curl test confirms that (for the UK lottery at least)
the numbers can be retrieved simply without the involvedment of javascript,
so Python will be able to do the same. (URL:
https://www.national-lottery.co.uk/player/p/results.ftl  Apologies if this
is about some other lottery and I've missed it...)
