Python os.path.join() on a list

I can do >>> os.path.join("c:/","home","foo","bar","some.txt") 'c:/home\\foo\\bar\\some.txt' But, when I do >>> s = "c:/,home,foo,bar,some.txt".split(",") >>> os.path.join(s) ['c:/', 'home', 'foo', 'bar', 'some.txt'] What am I missing here?
The problem is, os.path.join doesn't take a list as argument, it has to be separate arguments. To unpack the list into separate arguments required by join (and for the record: list was obtained from a string using split), use * - or the 'splat' operator, thus: >>> s = "c:/,home,foo,bar,some.txt".split(",") >>> os.path.join(*s) 'c:/home\\foo\\bar\\some.txt'
