📚 Student Marks Management System - NumPy Tutorial Python NumPy Jupyter
A comprehensive interactive Jupyter notebook demonstrating NumPy fundamentals through a practical student marks management system. This educational project covers array operations, statistical analysis, and data manipulation using real-world scenarios.
🎯 Project Overview This interactive notebook serves as a hands-on tutorial for learning NumPy by building a student marks management system. It covers essential NumPy concepts including array creation, manipulation, statistical operations, and practical data analysis with live code execution and visualizations.
✨ Features Module 1: Array Basics & Properties Creating NumPy arrays from Python lists Understanding array properties (shape, size, dtype, ndim) Comparing NumPy arrays with Python lists Module 2: Array Creation Functions Range-based Creation: arange(), linspace() Initialized Arrays: zeros(), ones(), empty(), full() Special Matrices: identity(), eye() Module 3: Array Manipulation Shape Operations: reshape(), flatten(), ravel(), transpose() Combining Arrays: concatenate(), vstack(), hstack(), hsplit() Modification: repeat(), flip(), delete(), unique() Type Conversion: astype(), copy(), view() Practical Application Statistical analysis (mean, sum, max, min, std) Student performance tracking Subject-wise analysis Top performer identification 🚀 Getting Started Prerequisites Python 3.6+ Jupyter Notebook or JupyterLab NumPy library Installation Clone the repository: git clone https://github.com/yourusername/numpy-student-marks-management.git cd numpy-student-marks-management Install dependencies: pip install numpy jupyter Running the Notebook Option 1: Jupyter Notebook
