Python provides straightforward approaches via standard libraries. These methods are concise and help you to write clean and exception-free code. 

Method 1: Using os.path.exists()

This method works across operating systems and returns True if the file (or directory) exists.

python

import os

file_path = “example.txt”

 

if os.path.exists(file_path):

    print(“File exists.”)

else:

    print(“File does not exist.”)

Works for both files and directories. Use os.path.isfile() to check specifically for files. 

Method 2: Using pathlib.Path.exists()

Introduced in python 3.4, It’s a more modern, object-oriented way to work with file paths.

python

from pathlib import Path

file = Path(“example.txt”)

 

if file.exists():

    print(“File exists.”)

else:

    print(“File does not exist.”)

Pathlib is preferred for newer codebases due to its clean syntax and better path handling.

Tip

  • To check only for files (not directories) use os.path.isfile() or file.is_file() in pathlib. 
  • Avoid using try-except just to test file presence; these methods are faster and more readable.
