当出现错误时，它会在 Python 上重试相同的用户名

Question

我的代码：import requestsfrom time import sleepfrom colorama import Forefile = [line.rstrip('\n') for line in open('myusername.txt')]count = 0URL = "https://127.0.0.1/ajax/attempt/"headers = {    'user-agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36'}for username in file:    count += 1    data = {        'firstname':'firstname',        'lastname' : 'lastname',        'username': username    }    r = requests.post(url = URL, headers=headers, data = data)    responde = r.text    print(responde)    if ('error_type' in responde):        print('{}[+]Trying ({}/{}) -{}{} Username: {} Taken{}'.format(Fore.WHITE, count, len(file), Fore.RESET, Fore.RED, username, Fore.RESET))    elif ('account_valid' in responde):        print('{}[+]Trying ({}/{}) -{}{} Username: {} Available{}'.format(Fore.WHITE, count, len(file), Fore.RESET, Fore.GREEN, username, Fore.RESET))    elif ('Please wait a few minutes before you try again.' in responde):        sleep(30)        print('{}[+]Waiting 30Sec for recheck ...{}'.format(Fore.YELLOW, Fore.RESET))当我的程序看到responde Please wait a few minutes before you try again它时，等待 30 秒并重试。但问题是，它会在服务器繁忙时绕过该用户名，并为下一个用户尝试。我希望在等待后出现服务器忙时，使用同一用户重试并继续..
