Python如何实现自动访问网页功能

import urllib.request
import requests
import time
import ssl
import random

def openUrl(ip, agent):
    headers = {'User-Agent': agent}    
    proxies = {'http' : ip}    
    requests.get("https://www.baidu.com", headers=headers, proxies=proxies, verify=True)    
    ssl._create_default_https_context = ssl._create_unverified_context    
    print("Access to success.")
