os.path.exists

os.path.exists() is a method in Python's os module that checks whether a path exists or not. It returns True if the path exists and False if it does not exist. The path can be a file or a directory.

For example, the following code checks whether a file named "example.txt" exists in the current directory:

import os

if os.path.exists("example.txt"):
    print("The file exists")
else:
    print("The file does not exist")

If the file "example.txt" exists in the current directory, the output will be "The file exists". Otherwise, the output will be "The file does not exist".
