There are things that If You Need Them You Know, and If You Do Not You 
Do Not Understand - and you seem to have found one.  The problem is that 
forums like this are not a statistically great sampling mechanism - a 
few dozen people, perhaps, chime in on many topics; there are millions 
of people using Python. Still, the folks here like to think they're at 
least somewhat representative :)

Hardware and software people may have somewhat different views of xor, 
so *maybe* the topic title added a bit to the muddle.  To me (one of 
those millions), any/all falsy, any/all truthy have some interest, and 
Python does provide those. Once you get into How Many True question - 
whether that's the odd-is-true, even-is-false model, or the 
bail-after-X-truthy-values model, it's not terribly interesting to me: 
once it gets more complex than an all/any decision, I need to check for 
particular combinations specifically. Two-of-six means nothing to me 
until I know which combination of two it is.
