My requirement, bringing me here, was to fill an SQL "WHERE x NOT IN ()" clause. The join() function will insert any string you like between elements but does nothing for each end of the list. So this works: nameString = '"{}"'.format('", "'.join(nameList)) Those are single quotes enclosing the desired double quoted strings. Python 3.7
