Python: Find Out If a File Exists or Not Using isfile() Function

To check if a file exists in Python, you can use the os module and the os.path.isfile() function. The os.path.isfile() function takes a file path as an argument and returns True if the file exists and is a regular file, and False if the file does not exist or is not a regular file.

Here's an example of how to use the os.path.isfile() function to check if a file exists in Python:

import os

# Check if a file exists
file_path = "path/to/file.txt"
if os.path.isfile(file_path):
    print("File exists")
else:
    print("File does not exist")

In this example, the os.path.isfile() function is used to check if the file at the specified path exists and is a regular file. If the file exists and is a regular file, the script will print File exists. If the file does not exist or is not a regular file, the script will print File does not exist.

It's important to note that the os.path.isfile() function only checks if the file exists and is a regular file. It does not check if the file is readable or writable, or if you have the necessary permissions to access the file. To check for these conditions, you can use other functions in the os module, such as os.path.exists(), os.access(), and os.stat().
