Python File Handling

Objective

Demonstrate understanding of Python file handling by completing the following tasks.

Tasks:

1. File Creation:

   • Create a Python script (file_handling_assignment.py) that does the following:
   • Creates a new text file named "my_file.txt" in write mode ('w').
   • Write at least three lines of text to the file, including a mix of strings and numbers.

2. File Reading and Display:

   • Enhance your script to read the contents of "my_file.txt" and display them on the console.

3. File Appending:

   • Modify the script to open "my_file.txt" in append mode ('a').
   • Append three additional lines of text to the existing content.

4. Error Handling:

   • Implement error handling using try, except, and finally blocks to manage potential file-related exceptions (e.g., FileNotFoundError, PermissionError).
