Python standard library OS module

(Mastering the OS module, you need to understand the operation of common commands under Linux or Unix-like systems)

os.name  Indicates the platform you are using. For example, for Windows, it is ‘nt‘ , and for Linux/unix users, it is ‘posix‘ .

os.getcwd() Gets the current working directory, which is the directory path of the current Python script work.

Os.mkdir (' path ') creates a new directory that is a string representing the path to the new directory.

Os.rmdir (' path ' ) removes the empty directory, path is a string that represents the path of the directory you want to delete. Equivalent to the $rmdir command.

Stat ( path ) looks for additional information about the file that the path points to, equivalent to the $ls-l command.

os.listdir( ‘.‘)  Returns all file and directory names under the specified directory. ' Represents the current path

os.remove( ‘path‘ )  Used to delete a file

Rename ( src, DST ) renames the file, SRC and DST are two paths, each representing the path before and after renaming.

chmod ( path, mode ) changes the permissions of the file that the path points to. Equivalent to the $chmod command.

Chown ( path, UID, GID ) changes the owner and owning group of the file that the path points to. Equivalent to the $chown command.

os.system()function to run the shell command.

Symlink ( src, DST ) creates a soft link for the file DST, src for the path of the soft link file. Equivalent to the $ln-s command.

os.path.split() The function returns the directory name and file name of a path.

>>> os.path.split (' ~/ETC/VIM/VIMRC ')
(' ~/etc/vim ', ' VIMRC ')

os.path.isfile() and os.path.isdir()  the function separately check whether the given path is a file or a directory.

Similarly, the os.path.existe() function is used to verify that the given path really exists

Shutil Bag

Copy (src, DST) copies files from Src to DST. Equivalent to the $CP command.

>>> Import Shutil
>>> shutil.copy (' aa.py ', ' bb.py ')

Move (src, DST) moves files from Src to DST. Equivalent to the $MV command.
