numpy numerical python

numpy tutorial: numerical python

numpy (numerical python) is one of the fundamental packages for numerical computing in python. it provides support for arrays, matrices, and a variety of mathematical functions to operate on these data structures.

key features of numpy

1. **n-dimensional arrays**: the primary feature of numpy is its powerful n-dimensional array object, `ndarray`.
2. **mathematical functions**: numpy provides a plethora of mathematical functions that operate on arrays.
3. **linear algebra**: it has built-in functions for linear algebra operations.
4. **random number generation**: numpy includes a module for generating random numbers.
5. **broadcasting**: numpy can perform operations on arrays of different shapes and sizes through broadcasting.

installation

before you can start using numpy, you need to install it. you can do this using pip:

importing numpy

to use numpy in your python code, you'll need to import it. it's common to import it with the alias `np`:

numpy provides various functions for aggregating data:

indexing and slicing

numpy allows you to access and modify array elements using indexing and slicing:

reshaping arrays

you can change the shape of an array using `reshape()`:

stacking and concatenating arrays

you can stack or concatenate arrays:

linear algebra

numpy provides functions for linear algebra:

conclusion

numpy is a powerful library for numerical computing in python. this tutorial covered the basics, including array creation, manipulation, mathematical operations, and linear algebra. as you dive deeper into data science and machine learning, you'll find numpy to be an essential tool in your toolkit.
