suggestions, comments on an "is_subdict" test

[Vlastimil Brom]

Thanks everyone for your opinions and suggestions!
I especially like the all(...) approaches of MRAB and Peter Otten,
however, the set conversion like
>>> set(test_dct.items()) <= set(base_dct.items())
True
looks elegant too.
In both approaches I can get rid of the negated comparison and the
additional "parsing cost" (for me reading it) is not that high.

As for the name,  I tried to make explicit (for this post), that both
the keys and their values are important in this test, but it doesn't
matter that much if is_subdict doesn't communicate this well
(probably?), as the "audience" of this code is not going to be anyone
but me.

Thanks for all the comments!
