Python: Test whether a given path exists or not
Python Operating System Services: Exercise-12 with Solution
Write a Python program to test whether a given path exists or not. If the path exist find the filename and directory portion of the said path.
Sample Solution:
Python Code :
import os
print("Test a path exists or not:")
path = r'g:\\testpath\\a.txt'
print(os.path.exists(path))
path = r'g:\\testpath\\p.txt'
print(os.path.exists(path))
print("\nFile name of the path:")
print(os.path.basename(path))
print("\nDir name of the path:")
print(os.path.dirname(path))
Sample Output:
Test a path exists or not: False False File name of the path: g:\\testpath\\p.txt Dir name of the path:

Previous: Write a Python program to iterate over a root level path and print all its sub-directories and files, also loop over specified dirs and files.
Next: Write a Python program to join one or more path components together and split a given path in directory and file.

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")
