<and> has a higher priority than <or> (as shown on the page you referenced -its "ascending priority"). Perhaps that could be clearer.
I find that brackets always make life easier in these cases (a rare statement in the Python world :-), and on a personal note I would always always comment heavily boolean operations that are not immediately obvious. it saves brain ache later on. >>> ((1 or 2) and 3) 3 However 1 or 2 and 3 is <1> if <and> is evaluated first. cheers On 10/10/05, Krishna <[EMAIL PROTECTED]> wrote: > >>> 1 or 2 and 3 > 1 > > Why does the above expression return 1?
