I'm not aware of anything that says it's bad form to define a function using a lambda when the only thing that a function does is immediately return some calculated value. > Anyway, it is probably clearer to use the builtin 'any' for code like this: > > >>> def hasvowels(s): > > ... return any(v in s for v in "aeiou") I wasn't aware of either "any" or "all". Thanks for the info! Unfortunately this recent project where I used "min" and "max" is running on a system using Python 2.4, so "any" and "all" are not available. > If you are doing a lot of this consider whether you might be better off > using sets: > > >>> def found(x,y): > > ... return bool(set(x).intersection(y)) I haven't used sets very much, but I'll definitely keep this in mind.
