At a quick glance your indenting is off to start. Is your values variable meant to be a integer or an array? Line 4 needs an indent or will throw a syntax error from the if statement.
Python doesn't allow arbitrary indentation. Top level code that isn't in a conditional block or function/class definition must not be indented.
It's a list of paths, with a list of values used in writeBlocking. That part is correct.
Thanks! Edit my post to fix.
As Phil said, you need to outdent your code. There is no def ... in your script so the line(s) shouldn't start with a tab or spaces. Move them all to column 1.
