Python: Get the size, permissions, owner, device, created, last modified and last accessed date time of a specified path

Python Operating System Services: Exercise-5 with Solution

Write a Python program to get the size, permissions, owner, device, created, last modified and last accessed date time of a specified path.

Sample Solution:

Python Code :

import os
import sys
import time
path = 'g:\\testpath\\'
print('Path Name ({}):'.format(path))
print('Size:', stat_info.st_size)
print('Permissions:', oct(stat_info.st_mode))
print('Owner:', stat_info.st_uid)
print('Device:', stat_info.st_dev)
print('Created     :', time.ctime(stat_info.st_ctime))
print('Last modified:', time.ctime(stat_info.st_mtime))
print('Last accessed:', time.ctime(stat_info.st_atime))

Sample Output:

Path Name (g:\testpath\):
Size: 546
Permissions: 0o100666
Owner: 0
Device: 4235770541

Previous: Write a Python program to check for access to a specified path. Test the existence, readability, writability and executability of the specified path.
Next: Write a Python program to create a symbolic link and read it to decide the original file pointed by the link.

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
