python通过mechanize模块实现不断刷新网页的功能，你可以通过命令行指定一个网页，程序将通过浏览器打开此页面并且不断的刷新，可以通过键盘随时终止，mechanize模块可以通过easy_install或者pip安装

import mechanize 
import sys 
  
def usage(): 
    print "Usage: python" + ' ' + sys.argv[0] + ' ' + "<url>" 
    sys.exit() 
  
def reloader(): 
    br = mechanize.Browser() 
    reload_count = 0 
    url = sys.argv[1] 
    start = br.open(url) 
  
    while True: 
        try: 
            br.reload() 
            reload_count += 1 
            print "[+] Sent reload request", "%s" % (reload_count) 
        except KeyboardInterrupt: 
            sys.exit("\nProcess aborted.") 
  
if len(sys.argv) < 2: 
    usage() 
  
if __name__ == "__main__": 
    reloader()
