#!/usr/bin/env python__author__="lrtao2010" #python3.7 OS module#an OS module is an interface that interacts with the operating system#OS.GETCWD () Gets the current working directory, which is the directory path of the current Python script work#Os.chdir ("dirname") changes the current script working directory, equivalent to the shell CD#Os.curdir Returns the current directory: ('. ')#Os.pardir Gets the parent directory string name of the current directory: (' ... ')#os.makedirs (' dirname1/dirname2 ') can generate multi-level recursive directories#os.removedirs (' dirname1 ') if the directory is empty, then delete, and recursively to the previous level of the directory, if also empty, then delete, and so on#os.mkdir (' dirname ') generates a single-level directory, equivalent to mkdir dirname in the shell#os.rmdir (' dirname ') delete the single-level empty directory, if the directory is not empty can not be deleted, error, equivalent to the shell rmdir dirname#os.listdir (' dirname ') lists all files and subdirectories in the specified directory, including hidden files, and prints as a list#os.remove () delete a file#os.rename ("Oldname", "newname") renaming files/directories#os.stat (' path/filename ') get File/directory information#OS.SEP output operating system-specific path delimiter, win under "\ \", Linux for "/"#os.linesep Output The line terminator used by the current platform, win under "\t\n", Linux "\ n"#os.pathsep output is used to split the file path of the string win down for;, Linux for:#The os.name output string indicates the current usage platform.

If path ends with a/or \, then a null value is returned.
