Except that you didn't read what Steven wrote, and you may not be
understanding your own code.  If the function fails it never returns
anyway, since an exception is raised!  So you don't need to worry about
a return type at all. You just do:

create_files_append()
do_something().

If you want to check for the exception, you would do:
try:
	create_files_append()
	do_something()
except OSError:
	do_next_thing()
