whenever i use the parse_quote function nothing happens and i just get a blank csv file but if i put all my quote items in parse funtion it is able to scrapy the quote what am i doing wrong?

def parse(self, response):
         
         #scraping only the page
          
          quotes  = response.xpath("//div[@class='quote']")
          
          for quote in quotes:
                self.parse_quotes(quote)
          

          #moving to the next page
          next_page = response.xpath("//li[@class='next']/a/@href").get()
         

          if next_page is not None:
             next_page_url = "https://quotes.toscrape.com/"+next_page
             
             #going to next page and then scraping the info of the page
             yield response.follow(next_page_url,callback=self.parse)

     
     
     # make a function to yield all the fields

     def parse_quotes(self, response):
       
        quote_item = QuoteItems()

        quote_item['Quote']  = response.xpath(".//span[@itemprop='text']/text()").get(),
        quote_item['Author'] = response.xpath(".//span//small[@class='author']/text()").get(),
        quote_item['Tags']   = response.xpath(".//div[@class='tags']//a[@class='tag']/text()").getall(),
        
        yield quote_item

Tried everything and am just tired from this problem
