Write a method , getemailusername, that is passed a string argument that is an email address and returns the user-name part. so if "mozart@salzberg. de" is passed, the method returns "mozart". assume that the argument will always be a correctly formatted email address.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
