是否可以从 JSON 文件中删除重复项？

Question

我有一个 JSON 文件，其中填充了抓取网站的数据。重复数据的次数比通常要多，例如，我提供了 JSON 文件外观的片段。是否可以删除重复项并保留第一次出现？用我的完整代码更新了最多。如果这有所作为。# grabs all the trending quotes for that daydef getTrendingQuotes(browser):    # wait until trending links appear, not really needed only for example    all_trendingQuotes = WebDriverWait(browser, 10).until(        lambda d: d.find_elements_by_css_selector('#trendingQuotes a')    )    return [link.get_attribute('href') for link in all_trendingQuotes]def getStockDetails(url, browser):    print(url)    browser.get(url)    quote_wrapper = browser.find_element_by_css_selector('div.quote-wrapper')    quote_name = quote_wrapper.find_element_by_class_name(        "quote-name").find_element_by_tag_name('h2').text    quote_price = quote_wrapper.find_element_by_class_name("quote-price").text    quote_volume = quote_wrapper.find_element_by_class_name(        "quote-volume").text    print("\n")    print("Quote Name: " + quote_name)    print("Quote Price: " + quote_price)    print("Quote Volume: " + quote_volume)    print("\n")    convertToJson(quote_name, quote_price, quote_volume, url)quotesArr = []# Convert to a JSON  filedef convertToJson(quote_name, quote_price, quote_volume, url):    quoteObject = {        "url": url,        "Name": quote_name,        "Price": quote_price,        "Volume": quote_volume    }    quotesArr.append(quoteObject)def trendingBot(url, browser):    browser.get(url)    trending = getTrendingQuotes(browser)    for trend in trending:        getStockDetails(trend, browser)    # requests finished, write json to file    with open('trendingQuoteData.json', 'w') as outfile:        json.dump(quotesArr, outfile)def Main():    scheduler = BlockingScheduler()    chrome_options = Options()    chrome_options.add_argument("--headless")    # applicable to windows os only    chrome_options.add_argument('--disable-gpu')
