Python 3.x 我得到了一个无效的语法错误的代码

我写了一个检查，并得到了这个错误，请我需要帮助：这是我得到的错误 文件“python1.py”，第14行 打印（f“登录成功e{email}&{password}”） ^ SyntaxError:无效语法

import requests
import multiprocessing
from multiprocessing.dummy import Pool



lock = multiprocessing.Lock()


class output(object):
    def screen(self, email, password, case):
        if case==True:
            lock.acquire()
            print(f"Login Success e {email} & {password}")
            print(f"""
                e = {email}
                p = {password}
                """, file=open("live.txt", "a"))
            lock.release()
        elif case==False:
            lock.acquire()
            print(f"Login Failed e {email} & {password}")
            lock.release()

您可能正在使用低于3.6的python版本来更新发布的fstring。您的解决方案是更新或依赖旧的trusty

str.format

方法：

class output(object):
    def screen(self, email, password, case):
        if case==True:
            lock.acquire()
            print("Login Success e {email} & {password}".format(email=email, password=password))
            print("""
                e = {email}
                p = {password}
                """.format(email=email, password=password), file=open("live.txt", "a"))
            lock.release()
        elif case==False:
            lock.acquire()
            print("Login Failed e {email} & {password}".format(email=email, password=password))
            lock.release()

您使用的是什么版本的Python 3？f-strings是在3.6中引入的您好，感谢您的提醒，我用您的代码替换了部分代码，并出现以下错误：“”。格式（电子邮件=电子邮件，密码=密码），文件=打开（“live.txt”，“a”）^SyntaxError:无效语法
