Hi Kyle,
Doh. I messed up here in the diagram. Forget those pictures above. I
meant to write:
l = ['', '', '', 'bb', 'bb', '']
'a'.join(l) ==>
'' + 'a' + '' + 'a' + '' + 'a' + 'bb' + 'a' + 'bb' + 'a' + ''
instead, which tries to show better the relationship that join() has with
split(). My apologies for being sloppy about this.
