关于伪装UserAgent知识总结

关于伪装UserAgent知识总结，可以根据自己实际应用环境去选择合适的节点，加入相应的代码即可：

1. 不缓存数据,不使用ssl 验证

from fake_useragent import UserAgent
 
ua = UserAgent(verify_ssl=False，use_cache_server=False)`

2. 禁用服务器缓存

from fake_useragent import UserAgent
 
ua = UserAgent(verify_ssl=False)

3. 问题：fake_useragent.errors.FakeUserAgentError: Maximum amount of retries reached

1. 新建一个文本文档并命名为XXX.json

2.打开这个文本文档，复制下面内容保存.

对于分析师来说，大家在学习Python数据分析的路上，多多少少都遇到过很多大坑**，有关于技能和思维的**：Excel已经没办法处理现有的数据量了，应该学Python吗？找了一大堆Python和Pandas的资料来学习，为什么自己动手就懵了？跟着比赛类公开数据分析案例练了很久，为什么当自己面对数据需求还是只会数据处理而没有分析思路？学了对比、细分、聚类分析，也会用PEST、波特五力这类分析法，为啥
Python中深拷贝与浅拷贝的区别 yuxiaoyu.

python中的深拷贝与浅拷贝 anshejd70787 python
深拷贝和浅拷贝浅拷贝的时候，修改原来的对象，浅拷贝的对象不会发生改变。1、对象的赋值对象的赋值实际上是对象之间的引用：当创建一个对象，然后将这个对象赋值给另外一个变量的时候，python并没有拷贝这个对象，而只是拷贝了这个对象的引用。当对对象做赋值或者是参数传递或者作为返回值的时候，总是传递原始对象的引用，而不是一个副本。如下所示：>>>aList=["kel","abc",123]>>>bLis
