I have seen the join method before but because of my lack of experience it didn't occur to me to use it. I bet I will remember it from now on. I stuck a few code examples into my 'snips' directory. Generator expressions are new to me. I have seen it's use but I didn't understand what it was and what it was doing, until now.
