A Linear Regression project that predicts student scores based on the number of hours studied. This project demonstrates the complete ML workflow: data preparation, model training, evaluation, and visualization.

• Python
• NumPy
• Pandas
• scikit-learn
• Matplotlib

• Feature vs target selection
• Train–test split
• Model training using Linear Regression
• Model evaluation using Mean Squared Error (MSE)
• Data visualization

• Linear Regression finds the best-fit straight line:

y = mx + c

• Hours_studied → Independent variable (X)
• score → Dependent variable (y)
• The model learns how study hours affect scores

A command-line password manager that securely stores and retrieves passwords using Fernet symmetric encryption. This project focuses on security fundamentals, encryption, and safe password handling.

• Python
• cryptography (Fernet)
• PBKDF2 key derivation
• OS file handling

• Master password protection
• Password-based key derivation (PBKDF2)
• Symmetric encryption (AES via Fernet)
• Secure password storage
