What is the error you are getting?

On certain objects id is a method, on others it is an attribute. The 
expression 'id != index_html' also tests if id (either a string or a method 
object) is equal to the object with id index_html.

Try this:

"if _['id'] != 'index_html'"

Which makes sure that is 'id' is a method, it is called and it's result is 
used. You then compare it to the string 'index_html'.
