File Read & Write 🖋️

This Python script reads a file, modifies its content, and writes the modified version to a new file. It also includes error handling to manage cases where the file doesn't exist or can't be read.

Features

• Reads a user-specified text file.
• Converts the content to uppercase (modification step).
• Writes the modified content to a new file prefixed with modified_.
• Handles errors gracefully, such as file not found or permission issues.

How to Use

1. Run the script:

   python file_modifier.py

2. Enter the filename when prompted.
3. If the file exists, a modified version will be created with a modified_ prefix.
4. If the file is missing or unreadable, the script will display an error message.

Example

Original File (example.txt)

Hello, world!
Python is great.

After Running the Script

Creates modified_example.txt:

HELLO, WORLD!
PYTHON IS GREAT.

Error Handling

• If the file doesn't exist:

  Error: File not found. Please check the filename and try again.
  

• If the file is unreadable:

  Error: Unable to read the file. Check permissions or file format.
  

Requirements

• Python 3.x
