无法建立新的连接：[WinError 10061]，循环从网站获取数据

Question

我正在编写代码，我需要每当第一个值等于“ ”时，它就会再次搜索，直到该值 >= 1，一旦达到，代码必须等待 19.97 秒才能返回搜索。

因为在这20秒的时间间隔内我将导出这些数据，并且它将是连续的数据，总是会覆盖过去的

from asyncio.windows_events import NULL
from ctypes.wintypes import PINT
from logging import root
from tkinter import N
from hyperlink import URL
from selenium import webdriver
import selenium
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support.expected_conditions import presence_of_element_located
import time

url = "https://blaze.com/pt/games/double"

#absolute path
firefox_driver_path = "/Users/Antônio/Desktop/roletarobo/geckodriver.exe"
firefox_options = Options()
firefox_options.add_argument("--headless")

webdriver = webdriver.Firefox(
    executable_path = firefox_driver_path,
    options = firefox_options
)
with webdriver as driver:
    # timeout
    wait = WebDriverWait(driver, 20)

    # retrieve data
    driver.get(url)

    #wait
    wait.until(presence_of_element_located((By.ID, "roulette-recent")))

    results = driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")
    for quote in results:
      quoteArr = quote.text.split('\n')

    print([my_elem.text for my_elem in driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")][:17])
    
    data = [my_elem.text for my_elem in driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")][:17]

while data[0] == '' or []:

    data = [my_elem.text for my_elem in driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")][:17]
    
else:
  time.sleep(19.97)

但是我只得到第一个结果，它无法再次连接到服务器

Answer 1

问题在于这一行：

while data[0] == '' or []:

您的数据[0]始终'' - ＆gt;循环永远运行，导致maxRetryError。
