How do I check that multiple keys are in a dict in a single pass?

I want to do something like: foo = { 'foo': 1, 'zip': 2, 'zam': 3, 'bar': 4 } if ("foo", "bar") in foo: #do stuff How do I check whether both foo and bar are in dict foo?
Well, you could do this: >>> if all(k in foo for k in ("foo","bar")): ... print "They're there!" ... They're there!
