args[1:] is a slice. So if args is a list, args[1:] is a list, if it's
a string, it's a string, etc... open expects a string -- as you
probably have already figured out.

So either you are passing the wrong argument: e.g. a list instead of a
string, or then, if you do want to pass a list then you have to change
your code. But now the course to follow depends on what you want to
do. So you have to explain a little more.

With my best regards,
