You cant concatenate a string to a list [1,2,3,4,5] + '\n', Try [1,2,3,4,5] + '\n' in the interpretor, you ll get the same error. write() doesn't know what to do with a list as [i think] it will only handle strings. If you wrap your list in str() for writing, that should do the trick Wouldn't hurt to wrap timeMark in str() also, unless your positive that the keys will always be strings store.write(str(timeMark) + '\n') store.write(str(aList) + '\n') HTH Good Luck, Glenn -- Ketchup.

His use of Python is at stake; he threatened that, since he's dependant enough on using perl -e within Emacs enough, if it can't be done in Python, he won't take the language seriously.
