yield unexpected expression syntax

I am creating a dictionary using yield, assigning a value to it seems to cause some kind of an error. My value for yield is a variable title which contains title = response.html("h1").extract()

import scrapy


class QuoteSpider(scrapy.Spider):
    name = "Quotes"
    start_urls = [
        "http://quotes.toscrape.com/"
    ]

    def parse(self, response):
        title = response.html("h1").extract()
        yield (' titletext ' : title)

I've tried replacing yield with return but that fails to extract the HTML. When I run the code, I get the error. SyntaxError: invalid syntax in yield (' titletext ' : title) What is the correct syntax for yield?

Without the error, I hope to be able to extract the h1 element from this website

I think you meant this:

yield { 'titletext': title }

The colon : means that it's a key-value pair, and that needs to go inside a dictionary, which is delimited by {} not ().
