Python 我跑得很慢

我正在尝试编写一个python脚本来检查百思买库存（如果可能的话，稍后再检查）。大约需要90秒才能完成。我不确定我使用selenium的方式是否有问题，或者我可以做些什么来提高性能。下面是日志。先谢谢你

from selenium import webdriver
import sys, time

def main():
    url = sys.argv[1]
    sku_t = 'skuId='
    sku = url[url.index(sku_t)+len(sku_t):]

    chrome_options = webdriver.ChromeOptions()
    chrome_options.headless = True
    chrome_options.add_argument('--window-size=1920,1080')
    prefs = {"profile.managed_default_content_settings.images": 2}
    chrome_options.add_experimental_option("prefs", prefs)
    driver = webdriver.Chrome(options=chrome_options)
    start_time = time.time()
    driver.get(url)
    print("--- %s seconds ---" %(time.time() - start_time))

    css_param = 'button.add-to-cart-button[data-sku-id="'+sku+'"]'
    add_to_cart_btn = driver.find_element_by_css_selector(css_param)
    print(add_to_cart_btn.text)
    driver.quit()

if __name__ == '__main__':
    main()

有一些API是专门为您提供的。如果您不想使用API，请尝试包括这些chrome\u选项

如果这些都不起作用，请尝试在没有headless模式的情况下运行脚本。 此外，您实际上不需要

selenium

来获取可用性和价格，因为它们存储在页面源代码中。因此，您也可以使用

requests

检查物品的可用性，并且仅在物品可用且您希望将其添加到购物车时调用

selenium

chrome_options.add_argument('--no-proxy-server')
chrome_options.add_argument("--proxy-server='direct://'")
chrome_options.add_argument("--proxy-bypass-list=*")
