Python: Find path refers to a file or directory when you encounter a path name

Python Basic: Exercise-108 with Solution

Write a Python program to find path refers to a file or directory when you encounter a path name.

Sample Solution:-

Python Code:

import os.path

for file in [ __file__, os.path.dirname(__file__), '/', './broken_link']:
    print('File        :', file)
    print('Absolute    :', os.path.isabs(file))
    print('Is File?    :', os.path.isfile(file))
    print('Is Dir?     :', os.path.isdir(file))
    print('Is Link?    :', os.path.islink(file))
    print('Exists?     :', os.path.exists(file))
    print('Link Exists?:', os.path.lexists(file))

Sample Output: 

File        : 26cb6a20-266f-11e7-a9c1-cf681af3cdf1.py              
Absolute    : False                                                
Is File?    : True                                                 
Is Dir?     : False                                                
Is Link?    : False                                                
Exists?     : True                                                 
Link Exists?: True  
------
Is Dir?     : False                                                
Is Link?    : False                                                
Exists?     : False                                                
Link Exists?: False

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")
