To check if a file exists at a specified folder in Python, you can use the os.path module. Here's an example code snippet that demonstrates how to do this:

import os

def check_file_exists(folder_path, file_name):
    """
    Check if a file exists at a specified folder.

    Args:
        folder_path (str): The path to the folder.
        file_name (str): The name of the file.

    Returns:
        str: A message indicating whether the file exists or not.
    """
    file_path = os.path.join(folder_path, file_name)  # Construct the file path
    if os.path.exists(file_path):  # Check if the file exists
        return f"The file '{file_name}' exists at '{folder_path}'."
    else:
        return f"The file '{file_name}' does not exist at '{folder_path}'."

# Example usage
folder_path = '/path/to/folder'
file_name = 'example.txt'
result = check_file_exists(folder_path, file_name)
print(result)
Python

In this code, the check_file_exists function takes two arguments: folder_path and file_name. It constructs the file path by joining the folder_path and file_name using os.path.join. Then, it uses os.path.exists to check if the file exists at the specified path. Finally, it returns a message indicating whether the file exists or not.

You can replace '/path/to/folder' and 'example.txt' with your desired folder path and file name. The result will be printed to the console.
