python has the ability to create a string from a sequence separated by a given 
delimiter.  in earlier pythons that capability is in the string module; later 
python, the string object itself had the method.

so

>>> import string
>>> mylist = ['s', 'p', 'a', 'm']
>>> string.join(mylist, '')
'spam'
>>> ''.join(mylist)
'spam'
>>> ','.join(mylist)
's,p,a,m'
>>>

hopefully with this bit you should be able to get what you want...
