大概这样吧。。题目自己整下，瞎编了几个

import json
def login():##登录并做题
    while True:
        name=input('输入账号：')
        password=input('输入密码：')
        print(name=="",len(password),len(password)<4)
        if name=="" or len(password)<4:
            print('账号不能为空并且密码需要大于4个字符，是否重新输入（y/n）？')
            cmd=input().lower()
            if cmd=="n":
                break
        else:
            for user in users:
                if user['name']==name and user['password']==password:##输入正确，做题
                    for q in qas:
                        print(q['q'])
                        if 'ans' in q:
                            an=input('请输入：')
                            q['ans'].append(an)
                        else:
                            an=input('请输入1（是），其他（否）')
                            if an=="1":
                                q['yes']+=1
                            else:
                                q['no']+=1
                    ##保存到文件
                    with open('qa.txt','w',encoding='utf-8') as f:
                        f.write(json.dumps(qas,ensure_ascii=False))
                    return##做完题目退出登录函数重新选择功能

            print('账号或密码错误，是否重新输入（y/n）？')
            cmd=input().lower()
            if cmd=="n":
                break
#查看统计结果
def showChoices():
    for qa in qas:
        if 'yes' in qa:
            print(qa['q'])
            print('是：',qa['yes'],'否：',qa['no'])

def search():
    s=input('输入关键词：')
    for qa in qas:
        if 'ans' in qa:
            if s in qa['q'] or s in '，'.join(qa['ans']):#关键字在题目中或者回答中输出
                print(qa['q'])
                for a in qa['ans']:
                    if s in a:
                        print(a)
