Python File Handling Project | Day 9 || AI WITH ALI HUSNAIN

Welcome to *Day 9* of the Python Zero to Hero Series! 🚀

Boring theory ka time khatam! Aaj hum banayenge ek *Real World Project* using Python File Handling. Aaj hum Python ko ek "Permanent Memory" denge taaki program band hone ke baad bhi aapka data safe rahe.

In this video, we will build a *"Secret Notes Manager"* app. Whether you want to save student records, game scores, or your personal secrets—this concept is the key! 🔑

*🔥 What you will learn in this video:* ✅ How to build a persistent Data Storage system.
✅ Reading (`r`), Writing (`w`), and Appending (`a`) in real projects.
✅ The "Best Way" to handle files using the `with` keyword.
✅ How to avoid Memory Leaks and Errors.

*👨‍💻 YOUR HOMEWORK (Mission):* Maine video mein Note Likhna (Write) aur Padhna (Read) sikhaya hai.
Aapka task hai ek *"Delete/Clear All"* feature add karna!
Agar file ka saara data clear kar diya, toh comment mein likhna:
👉 *"Mission Successful! I cleared the file!"* 😎
