Exercise 1.24: Putting it all back together

Want to take a list of strings and join them together into one string? Use the join() method of strings like this (note: this looks funny at first).

>>> a = ','.join(symlist)
>>> a
'YHOO,RHT,HPQ,GOOG,AIG,AAPL,AA'
>>> b = ':'.join(symlist)
>>> b
'YHOO:RHT:HPQ:GOOG:AIG:AAPL:AA'
>>> c = ''.join(symlist)
>>> c
'YHOORHTHPQGOOGAIGAAPLAA'
>>>
