yes indeed!

if we had questioned python for: "k" in (name and year and month)

that would have returned the argument month back which is "efgh" and 
then the if would have evaled to false since 'k' isn't part of the latter.

"k" in (name and month and year) != "k" in (name and year and month)

As wee see, the order of the arguments in an expression matters.
