Import OS

Print (OS.GETCWD ()) #获取当前工作目录, the directory path where the current Python script works

Os.chdir ("F:\python devops Development \day4") #改变当前的工作目录: equivalent to the shell CD
Print (OS.GETCWD ()) #结果F: \python devops Development \day4

Os.chdir (Os.curdir) #返回当前目录:(.): equivalent to the shell CD.
Print (OS.GETCWD ())

Os.chdir (os.pardir) #返回当前父目录:(...): equivalent to the shell under the CD.
Print (OS.GETCWD ())

Os.makedirs ("Day6/test") #可生成多层递归目录: equivalent to the shell mkdir-r Day6/test, the directory has an error
Os.removedirs ("Day6/test") #删除多层递归目录: equivalent to Shell under RM-RF day6/test

#os. mkdir ("Day6") #可生成单级目录: equivalent to shell mkdir Day6
#os. RmDir ("Day6") #可删除单级目录: equivalent to Shell rm-f Day6

Print (Os.listdir ("F:\python devops Development")) #列出指定目录下的所有文件和子目录, including hidden files, and printed in a list ls-a

Os.chdir ("F:\python devops Development \day6")
#os. Remove ("1.py") #删除文件
#os. Rename ("2.py", "1.py") #重命名文件
Print (Os.stat ("1.py")) # Get file or directory information
Print (OS.SEP) #输出操作系统特定的路径分隔符, win under "\ \", Linux for "/"
Print (OS.LINESEP) #输出当前平台使用的行终止符, win under "\t\n", Linux "\ n"
Print (OS.PATHSEP) #输出用于分割文件路径的字符串, win down for (:)
Print (Os.name) #输出字符串指示当前使用平台. Win-> ' NT '; Linux-> ' POSIX '
Os.system ("Ls-l") #运行shell命令, direct display
Print (Os.environ) # Get System environment variables
Print (Os.path.abspath (os.curdir)) #返回path规范化的绝对路径
Print (Os.path.split (' F:\python devops Development \day6\\test1.py ')) #将path分割成目录和文件名二元组返回
Print (Os.path.basename (' F:\python devops Development \day6\\test1.py ')) #返回path的目录. is actually the first element of Os.path.split (path)
Print (Os.path.dirname (' F:\python devops Development \day6\\test1.py ')) #返回path最后的文件名. If path ends with a/or \, then a null value is returned. The second element of Os.path.split (path)


Print (Os.path.exists ("F:\python devops Development \day6")) #如果path存在, returns True if path does not exist, returns false

Print (Os.path.isdir ("F:\python devops Development \day6")) #如果path是一个存在的目录, returns True. otherwise returns false

Print (Os.path.join (Os.curdir, "1.py")) # Returns a combination of multiple paths, and the parameters before the first absolute path are ignored

Print (Os.path.getatime (os.curdir)) # Returns the last access time of the file or directory pointed to by path, which is a timestamp
Print (Os.path.getmtime (os.curdir)) # Returns the last modification time of the file or directory pointed to by path, which is a timestamp
