Numpy Python Tutorial | Numpy Indexing and Slicing | Numpy Broadcasting

Web Reference: NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more. The only prerequisite for installing NumPy is Python itself. If you don’t have Python yet and want the simplest way to get started, we recommend you use the Anaconda Distribution - it includes Python, NumPy, and many other commonly used packages for scientific computing and data science. NumPy documentation # Version: 2.4 Download documentation: Historical versions of documentation Useful links: Home | Installation | Source Repository | Issue Tracker | Q&A Support | Mailing List NumPy is the fundamental package for scientific computing in Python.

YouTube Excerpt: In this video, you’ll learn about how to perform indexing, slicing and broadcasting using the Numpy Python Library. This library is essential to Machine Learning as it allows you to efficiently work with data through arrays and matrices! You’ll learn how to perform selection of an array through square brackets, how to utilize Slicing to obtain specific values of your array, how to perform indexing and selection on both 1D arrays and 2D arrays, how to broadcast a value to the entire array as well as specific portions, how to create a copy of an array, and how to relate Booleans and arrays to filter your array based on specific conditions. After watching this video and learning the basics of indexing using Numpy, there’s an activity right below this description for you to try out on your own using the skills you learned here. Enjoy! NUMPY ACTIVITY: Create a random 2 dimensional Numpy array and change the upper right corner to display ‘hi’, while keeping the rest of the matrix the same.
