在服务器上挂载OSS_bucket

最近想做个关于tf-idf的实验，找了好多代码都用到了sklearn库，今天先来简单了解一下。sklearn共分为6大部分，分别用于完成分类任务，回归任务，聚类任务，降维任务，模型选择以及数据的预处理。分类任务回归任务聚类任务降维任务...

就两部分内容，瞄一眼就行十、文件和异常1、从文件中读取数据#1-读取整个文件with open(test.txt) as file_object: contents=file_object.read() print(contents）#2-文件路径：相对于当前目录，也可以填写绝对路径with open(test/test.txt) as file_object:#3-逐行读取文件with open(test.txt) as file_object: for l

二 变量与简单数据类型2.3 字符串 大小写：title(首字母大小写)，upper(大写)，lower(小写) 拼接：+ 添加空白：\t 删除末尾空白：rstrip() 剔除开头空白：lstrip() 同时剔除两端空白：strip() Python3：print() 必须加括号，Python2可以不用加 2.4 数字 print中使用str()避免类型错误 3/2=1，3.0/2=1.5 三 列表 [ ]

总体很简单，就是想复习复习，找找被自己遗漏的知识点六 字典1、格式：alien={'color':'green','points':5}2、添加键值对：alien['x_position']=03、创建一个空指点：alien={}4、删除键值对：del alien['points']5、遍历字典：for key, value in alien.items():对于key, value这两个变量，可以使用任何名称6、遍历字典中的所有键：for name in alien.key
