login_user = relationship('LoginUser',backref=backref('user',uselist=False))

老师您能详细解释一下两个backref都是什么意思吗，这块不理解

还有为什么

user = relationship('User',uselist=False)

在LoginUser中设置后在，在user.login_user查询的时候返回的也不是列表

老师，请问全局变量global的声明在函数里声明，和在函数的循环里声明有什么区别

这是人人车的价格加密后，进行破解的方法：

../config最后的结果不一样，按照步骤操作之后还是显示没有安装成功

老师，您帮我看下，我这代码里有bug，先输入一次错误的，在输一次正确的以后就不跳出循环，但如果一开始就输入正确的就会跳出循环

import re
def e_mail():
    s = input('请输入qq邮箱：')
    pattern = r'[1-9]\d{4,8}@qq.com$'
    result = re.match(pattern, s)
    while True:
        if result:
            print('验证成功')
            break
        else:
            print('验证失败，请重新输入')
            e_mail()
e_mail()

防抖和节流在哪里讲的啊

2020-01-30

为什么客户端和服务器端都没有反应？端口号怎么挑选？

未找到virtualenvwrapper虚拟环境安装配置过程

课上用的mysql jar包是从哪里下载的

不讲讲cpu吗，我电脑没有gpu

没实现群聊功能的时候   我要客户端发送的消息，，服务器能够显示消息内容

代码该怎么写

老师，我试着输入了一个负数执行continue语句，进入新的循环会用掉一次循环的次数，导致并没有成功输入4名员工的工资，这个要怎么完善？

empNum = 0
salarySum = 0
salarys = []
for i in range(4):
    s=input('请输入4名员工的薪资（按Q或者q结束）')
    if s.upper()=='Q':
        print('录入结束')
        break
    if float(s)<0:
        # print('无效，请重新输入！')
        continue
    #print('录入成功')
    empNum += 1
    salarys.append(float(s))
    salarySum += float(s)
else:
    print("您已经全部录入4名员工的薪资")
print('员工数量{0}'.format(empNum))
print('录入薪资：',salarys)
print('总薪资：',salarySum)
print('平均薪资{0}'.format(salarySum/empNum))

为什么？

明明comp.computer已经赋值了，

将comp的值赋值给comper可打印的结果却是那个类方法的名称
