As I understand it, registered trademarks are handled by legislation,
whereas passing off is handled by case law. Registered trademarks are
infringed if a mark is registered as specified, and used in a way
described in the act as restricted. Passing off is a vaguer offence
that occurs if you impersonate someone else or their product. There
are various summaries in civil court decisions:
Lord Diplock in Warnink v Townend (1980) RPC 31 at 93 identified,
from the cases decided before l980, five characteristics which had
to be present. He said: "My Lords, Spalding v Gamage and the later
cases make it possible to identify five characteristics which must
be present in order to create a valid cause of action for passing
off: (1) a misrepresentation (2) made by a trader in the course of
trade (3) to prospective customers of his or ultimate consumers of
goods or services supplied by him, (4) which is calculated to injure
the business or goodwill of another trader (in the sense that this
is a reasonably foreseeable consequence) and (5) which causes actual
damage to a business or goodwill of the trader by whom the action is
brought or (in a quia timet action) will probably do so." -- British

I suggest that a) may not be trademark infringement because the
language is also called Python and Debian contains an implementation
of that language. A clueful distributor would say something like c)
it contains a python interpreter, but I agree that the standard of
distributor responses to these questions is sometimes not great.
I don't think Debian needs to warn its distributors - they should
already have noticed they are swimming in trademark-infested water,
thanks to the bugs about the debian trademark!

Does a trade mark exist without trade?

It depends why you are giving them away, but it may not be a trademark
offence. (It may still be all other sorts of offence.)

I think that's almost certainly OK - it seems similar to the discount
mystery cases of wine that people buy from firms like Laithwaites.
Sometimes it's the real deal, sometimes it's a near relative or the
vineyard next door.

It's not quite that, but I can't figure out how the project would be
infringing the Python trademark in this situation.
Hope that explains,
