北京四维图新科技股份有限公司4月招聘面试题面试题面试官常问到的一些题目整理如下:问题 Q1:是否使用过functools中的函数?其作用是什么?可用的回答 :python自带的 functools 模块提供了一些常用的高阶函数,也就是用于处理其它函数的特殊函数。换言之,就是能使用该模块对可调用对象进行处理。functools.cmp_to_key(func)functools.total_ordering(cls)functools.reduce(function, iterable, initializer)functools.partial(func, args, *keywords)functools.update_wrapper(wrapper, wrapped, assigned, updated)functools.wraps(wrapped, assigned, updated)问题 Q2:用尽量多的方法实现单例模式?可用的回答 : 一、模块单例 Python 的模块就是天然的单例模式,因为模块在第一次导入时,会生成.pyc文件,当第二次导入时,就会直接加载.pyc文件,而不会再次执行模块代码。 二、静态变量方法 先执行了类的_new_方法(我们没写时,默认调用object._new_),实例化对象; 然后再执行类的_init_方法,对这个对象进行初始化,所有我们可以基于这个,实现单例模式。 class Singleton(object): def _new_(cls,a): if not hasattr(cls, _instance): cls._instance = object._new_(cls) return cls._instance def _init_(self,a): self.a = a 问题 Q3:大数据的文件读取?可用的回答 : 1. 利用生成器generator 2. 迭代器进行迭代遍历:for line in file 问题 Q4:什么是反射?以及应用场景?可用的回答 : 通过字符串获取对象的方法称之为反射 python中可以通过如下方法实现: 1. getattr 获取属性 2. setattr 设置属性 3. hasattr 属性是否存在 4. delattr 删除属性 问题 Q5:Django 本身提供了 runserver,为什么不能用来部署?可用的回答 : runserver 方法是调试 Django 时经常用到的运行方式, 它使用 Django 自带的 WSGI Server 运行,主要在测试和开发中使用,并且 runserver 开启的方式也是单进程 。 uWSGI 是一个 Web 服务器,它实现了 WSGI 协议、uwsgi、http 等协议。 注意 uwsgi 是一种通信协议,而 uWSGI 是实现 uwsgi 协议和 WSGI 协议的 Web 服务器。 uWSGI 具有超快的性能、低内存占用和多 app 管理等优点, 并且搭配着 Nginx就是一个生产环境了,能够将用户访问请求与应用 app 隔离开,实现真正的部署 。 相比来讲,支持的并发量更高,方便管理多进程,发挥多核的优势,提升性能。 问题 Q6:遇到反爬机制怎么处理?可用的回答 : 反爬机制: headers方向 判断User-Agent、判断Referer、判断Cookie。 将浏览器的headers信息全部添加进去 注意:Accept-Encoding;gzip,deflate需要注释掉 问题 Q7:Django 本身提供了 runserver,为什么不能用来部署?可用的回答 : runserver 方法是调试 Django 时经常用到的运行方式, 它使用 Django 自带的 WSGI Server 运行,主要在测试和开发中使用,并且 runserver 开启的方式也是单进程 。 uWSGI 是一个 Web 服务器,它实现了 WSGI 协议、uwsgi、http 等协议。 注意 uwsgi 是一种通信协议,而 uWSGI 是实现 uwsgi 协议和 WSGI 协议的 Web 服务器。 uWSGI 具有超快的性能、低内存占用和多 app 管理等优点, 并且搭配着 Nginx就是一个生产环境了,能够将用户访问请求与应用 app 隔离开,实现真正的部署 。 相比来讲,支持的并发量更高,方便管理多进程,发挥多核的优势,提升性能。 问题 Q8:如何跨模块共享全局变量?可用的回答 :要在单个程序中跨模块共享全局变量,请创建一个特殊模块。在应用程序的所有模块中导入配置模块。该模块将作为跨模块的全局变量提供。问题 Q9:说说什么是爬虫协议?可用的回答 : Robots协议(也称为爬虫协议、爬虫规则、机器人协议等)也就是robots.txt, 网站通过robots协议告诉搜索引擎哪些页面可以抓取,哪些页面不能抓取。 Robots协议是网站国际互联网界通行的道德规范,其目的是保护网站数据和敏感信息、确保用户个人信息和隐私不被侵犯。因其不是命令,故需要搜索引擎自觉遵守。 问题 Q10:什么是序列化和非序列化?可用的回答 :Pickle模块接受任何Python对象并将其转换为字符串表示形式,并使用dump函数将其转储到文件中,此过程称为pickling。从存储的字符串表示中检索原始Python对象的过程称为unpickling算法题面试官常问到的一些算法题目整理如下(大概率会机考):算题题 A1:合并K个已排序过的链表题目描述如下:Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity.Example:Input: 1-4-5, 1-3-4, 2-6Output: 1-1-2-3-4-4-5-6合并 k 个有序链表。用了最小堆:把所有的链表节点入堆,然后出堆形成新的链表即可。依然依靠了内置模块,待自己书写堆。测试地址:h

有关 Assigned的说法哪个是正确的?( )

C.Assigned的参数可以是对象或者方法,或者是一个指针

D.Assigned的作用是判断 Assign过程是否已经完成。

I don’t think it advisable that Tim( )to the job since he has no experience.

A.is assigned
B.will be assigned
C.be assigned
D.has been assigned

答案:C
解析:
考查虚拟语气。在It is advisable/important ...that ...的句型中,that 引导的主语从句中的谓语应用虚拟语气,形式为“(should) +动词原形”,should 可省略。故本题选C。句意:我认为指派蒂姆做这项工作是不明智的,因为他没有经验。
