Does python check the data in the database and return no data?

def process_item (self, item, spider):

print("")

print(item["file_url"], item["name"])

key_word = {"file_url": "asdasdasd", "name": "asdasdadas"}
res = self.db.find(key_word)
print("")
print(res)
if res:
    print("")

    raise DropItem("Duplicate item found: %s" % item)
else:
    print("*******************************************************************************")
    self.db.insert({"file_url": item["file_url"], "name": item["name"]})

    return item

db.XiaoMiQuan.find ()
{"_ id": ObjectId ("5bbf14dbc96b5b3f5627d11d"), "file_url": "https://baogaocos.seedsufe.com/2018/07/19/doc_1532004923556.pdf"," name ":" AMCHAM- China"s "Belt and Road Initiative": impact on American Enterprises (English)-2018.6-8 pages. Pdf "}
