In case you are feeling that the ','.join(l) looks a bit jarring, be aware 
that there are alternative ways to write it. You can call the method on the 
class rather than the instance:

   jl = str.join(',', l)
   jl = unicode.join(u'\u00d7', 'l')

has the advantage of looking almost the same as the string function except 
that the order of the arguments is reversed, the catch is you need to know 
the type of the separator in advance. If you have a lot of calls with the 
same separator then you can also save the method in an appropriately named 
variable:

   commaseparated = ','.join
   ...
   jl = commaseparated(l)
