File Error Exceptions

File I/O Error handling in Python.

Python - File Error Handling:

Error handling in Python involves using try-except blocks to catch and handle exceptions that might occur during the execution of your code. Here's a basic example of how you can handle errors in Python files:

example.txt
txt (Text File) Copy Code
File error handing in Python.
main.py
PDF Copy Code
try:
    # Open the file
    with open("example.txt", "r") as file:
        # Read the contents of the file
        contents = file.read()
        # Print the contents
        print(contents)
except FileNotFoundError:
    # Handle the case where the file is not found
    print("File not found!")
except IOError:
    # Handle other input/output related errors
    print("An error occurred while reading the file.")
except Exception as e:
    # Handle any other exceptions
    print("An unexpected error occurred:", e)
Output:
File error handing in Python.

Explanation:

1. We attempt to open a file named "example.txt" in read mode.

2. If the file is not found, a 'FileNotFoundError' will be raised.

3. If any other input/output error occurs during file reading, an 'IOError' will be raised.

4. If any other unexpected error occurs, it will be caught by the generic 'Exception' block.

You can customize the except blocks to handle different types of errors as per your requirements. Make sure to handle exceptions gracefully to prevent crashes and provide meaningful error messages to users.
