the 'in' operator searches for existance of *elements* in a set, not of
*subsets*. BTW, only a frozenset can be included in a set.
To check for subsets, either use the issubset function, or the '<' operator (I
believe they both call the same code):
can be expressed as
.>> set(['TRUE','YES']) < set(dir(Tkconstants))
TZOTZIOY, I speak England very best.
"Be strict when sending and tolerant when receiving." (from RFC1958)
I really should keep that in mind when talking with people, actually...
