    Stupid Notepad

    Stupid Notepad

    The Simplest Notepad Ever

    ...Because it's extremely simple and primitive, making it understandable for everyone! The interface consists of just seven elements: - Text field for entering the file path; - "Browse..." button; - "Open" button; - "New" button; - "Save" button; - Text field for viewing and editing the file's text; - "Exit" button. This is my first even slightly useful Python program, so I'd be grateful if you'd test it and see if this stupid notepad proves useful! Stupid Notepad is an open source project. You can read the code in "Stupid Notepad.py" in this folder or visit GitHub: github.com/artemik01/stupid-notepad
