You're not making any sense. The sequence argument is not listed and the lambda is unnecessary. Try this instead: any(x[3] == 'thiskey' for x in seq) > I think it makes a lot of sense for any and all to take optional > predicate function arguments. I think you don't understand what you already have to work with in Py2.5a -- a boolean expression in a genexp should always suffice -- no separate lambda based predicate function is ever required.
