我怎样才能摆脱循环呢?

loops python

所以我一直在试着和monitor一起玩ABIT——对于那些不知道monitor是什么的人来说——基本上这意味着你在一段时间内检查了某个元素、url或者其他什么东西,然后再次检查它是否被更改了。

这就是我所做的…

url = 'mrcnoir'

while True:
        try:
            password_page = requests.get('https://{}.com'.format(url), timeout=5)
            password_page.raise_for_status()

        except requests.exceptions.RequestException as err:
            print('Error checking password page! - https://{}.com'.format(url) + ' - ' + str(err))
            continue



        else:
            # *************---If password up---**************

            if ('password' in password_page.url):
                        # Password page is up
                        print('Password page is up! - ' + 'https://{}.com'.format(url))
                        if not ('password' in password_page.url):

                            # No password page -> password page


                            # *************---Send---**************

                            print("SENDING...1")

                            time.sleep(random.randint(6, 12))


            # *************---If password down---**************

            else:
                # Password page is down
                print('Password page is down! - ' + 'https://{}.com'.format(url))
                if ('password' in password_page.url):

                    # Password page -> no password page


                    # *************---Send---**************

                    print("SENDING...2") #<---- If it comes in here - it will be stuck forever and just keep posting this print...
                    time.sleep(random.randint(6, 12))

        # *************---Retry between 6-12 random.---**************
        finally:
            time.sleep(random.randint(6, 12))

我遇到的问题是它在底部打印“sending…2”-发生的是它一直在继续打印“sending…2”,这意味着它一直卡在循环中。-

基本上,我想做的是,每当涉及到第二部分时,它应该打印一次,然后继续“监视”并检查,直到有新的变化。这意味着它需要等待,直到它在URL中出现/密码。

在这种情况下,我怎么能做到?
