Python Learning Notes--common object methods for OS modules

1 #here is a list of the functions used in the OS module for files/directories2 3 #note here that before using these methods, remember to import the OS module4 ImportOs#Import OS module5 """6 OS Object methods:7 os.getcwd () #返回当前工作目录8 os.chdir (path) #改变工作目录9 Os.listdir (path= ".") #列举指定目录中的文件名 ("." Represents the current directory, "..." Indicates the previous level of the directory)Ten os.mkdir (Path) #创建建单层目录, throws an exception if the directory already exists One os.makedirs (path) #递归创建多层目录, if a thrown exception already exists in the directory, A os.remove (path) #删除文件 - os.rmdir (Path) #删除单层目录, throws an exception if the directory is not empty - os.removedirs (Path) #递归删除目录, from sub-directory to parent directory by layer, try to delete, encountered directory non-empty throws an exception the os.rename (old,new) #将文件old重命名为new - os.system (command) #运行系统shell命令 - os.walk (top) #遍历top路径以下所有子目录, returns a ternary group: (Path, [contains directory],[include file]) - Os.curdir #属性 that represents the current directory + Os.pardir #属性, indicating the previous level of directory - os.sep #属性, output operating system-specific path delimiter (win under ' \ \ ', Linux as '/') + Os.linesep #属性, the line terminator used by the current platform (win under ' \ r \ n ', Linux ' \ n ') A Os.name #属性 refers to the operating system that is currently in use at      - Os.path Object methods: - os.path.basename (path) #去掉目录路径, return file name separately - os.path.dirname (path) #去掉文件名, return the directory path separately - Os.path.join (path1[,],path2[,...]) #将path1, path2 parts form a path name - os.path.split (path) #分割文件名和路径, returns a (f_path,f_name) tuple that separates the last directory as a file name if the directory is fully used in os.path.splitext (path) #分离文件名和后缀名, returns the (f_name,f_extension) tuple, which separates the last directory as the file name if the directory is fully used - os.path.getsize (file) #返回指定文件的尺寸, Unit is byte to os.path.getatime (file) #返回指定文件最近的访问时间 (floating-point number of seconds, gmtime () or localtime () function of the time module can be converted) + os.path.getctime (file) #返回指定文件的创建时间 - os.path.getmtime (file) #返回指定文件最新的修改时间 the os.path.exists (path) #判断指定路径是否存在 (directory or file) * os.path.isabs (path) #判断是否为绝对路径 $ os.path.isdir (path) #判断指定路径是否存在且是一个目录Panax Notoginseng os.path.isfile (path) #判断指定路径是否存在且是一个文件 - os.path.islink (path) #判断指定路径是否存在且是一个符号链接 the os.path.ismount (path) #判断指定路径是否存在且是一个挂载点 + os.path.samefile (path1,path2) #判断path1, does path2 point to the same file A          the """
