The OS module of the Python module

OS Module

A module that the Python interpreter interacts with the operating system. Used to manipulate directories and files.

# get current working directory Print (OS.GETCWD ())

# Change Directory os.chdir ('C:')print(OS.GETCWD ())  #  C +

Os.chdir (Os.curdir)  # ' . ' Go to the current directory Os.chdir (os.pardir)  #  ': ' Go to the parent directory

 os.makedirs ( " a/b/c  " ) #   Create multilevel directory  Os.removedirs ( '  a/b/c    ") #   Os.mkdir ( " a  " ) #   Create a single-level directory  Os.rmdir ( '  a     ") #   Delete single-level directory, empty delete, otherwise error! 

Print (Os.listdir ())  # lists all files and subdirectories under the specified directory, including hidden files, and prints as a list

Os.remove (file)  #  Delete file os.rename ('a''b ')  # Rename the file, the folder is empty can also be renamed, not empty error os.renames ('test/a'test1/ b')  #  You can name both the folder and the following file

Os.stat ('path/file')  #  Get File/directory information

Os.sep  #  Output operating system-specific path delimiter win under "\ \", Linux under "/"os.linesep  #  outputs the line terminator used by the current platform, Win under "\t\n", Linux under "\ n"os.pathsep  #  output is used to split the file path of the string win under; Linux is:

Print (os.name)  # The output string indicates the current usage platform. Win-> ' NT '; Linux-> ' POSIX' os.system ('dir')  #  run shell command, direct display  Print(Os.popen ('dir'). Read ())  #  Run the shell command to get the result of the execution  Print(os.environ)  #  get system environment variables

Os.path.abspath ('Path')#gets the absolute path of pathOs.path.split ('Path')#A tuple that splits path into directories and file names returnsOs.path.dirname ('Path')#the first element of a tuple that is equivalent to Os.path.split (' path ') splitOs.path.basename ('Path')#equivalent to the second element of a os.path.split (' path ') split tupleOs.path.exists ('Path')#determines if path exists, exists return true, does not exist return FalesOs.path.isabs ('Path')#determine if path is an absolute pathOs.path.isfile ('Path')#determine if path is a fileOs.path.isdir ('Path')#determine if path is a directoryOs.path.join ('path1','path2','Path3')#combine multiple paths togetherOs.path.getsize ('Path')#Gets the size of the path, the size of the directory to calculate the size of the files below him .Os.path.getatime ('Path')#returns the last access time of the file or directory pointed to by path, in the form of a timestampOs.path.getmtime ('Path')#returns the last modified time of the file or directory pointed to by path, in the form of a timestamp
