This tutorial will guide you through various methods to check if a file exists in Python, along with code examples. Method 1: Using the os.path Module The os.path module provides a function called exists(), which can be used to check if a file exists. Here's a simple example: Method 2: Using the pathlib Module (Python 3.4 and later) The pathlib module, introduced in Python 3.4, provides an object-oriented interface for file system paths. The Path class has a exists() method for checking file existence: Method 3: Using the try...except Block (Python 3.2 and later) You can use a try...except block to handle the FileNotFoundError exception when trying to open the file: Choose the method that best fits your needs and the Python version you are using. These approaches will help you determine whether a file exists before proceeding with other file-related operations in your Python scripts. ChatGPT
