Full python numpy with one project

## a comprehensive tutorial on numpy

### what is numpy?

numpy (numerical python) is a powerful library for numerical computing in python. it provides support for arrays, matrices, and a plethora of mathematical functions to operate on these data structures efficiently. it's the foundational library for many other scientific computing libraries such as pandas, scipy, and matplotlib.

### key features of numpy

1. **n-dimensional arrays**: provides support for multi-dimensional arrays and matrices.
2. **mathematical functions**: includes a wide range of mathematical functions to operate on arrays.
3. **linear algebra**: offers tools for linear algebra operations.
4. **random number generation**: provides functionalities to generate random numbers.
5. **integration with other libraries**: works seamlessly with other libraries like pandas and matplotlib.

### installation
