Getting Started with Numpy Arrays in Python [ID:1037]

a series of video-tutorials by unpingco

Numpy is the foundation of most of the scientific computing in Python. In this series, we examine the many important features of numpy and how they can be used to facilitate scientific computing in Python.

Video Tutorials

1. Introducing Numpy Arrays

In this segment, we discuss how to create and use simple numpy arrays.

2. Using numpy dtypes

In this segment, we discuss additional ways to create numpy arrays and how to use powerful numpy dtypes (data types) in numpy arrays.

3. Numpy data input/output

In this segment, we discuss how you can read in numpy arrays from files under various conditions.

4. Using Numpy Arrays: Slicing, Logical Array Operations, and Math

In the segment, we discussed manipulating numpy arrays using slicing and logical operations, as well has how to use numpy's wealth of built-in optimized math functions.

5. Linear Algebra with Numpy

In this segment, we discuss how to do linear algebra with numpy matrices and arrays.

6. Numpy Masked Arrays

In this segment, we discuss the distinctive and powerful masked array numpy type that allows for selective suppression of array entries.

7. Broadcasting Numpy Arrays

In this segment, we discuss numpy broadcasting by which arrays of different shapes can be intuitively combined.

8. Using Numpy Temporary Variables

In this segment, we discuss how you can use numpy temporary variables to control memory constrained calculations.

9. Functional Programming Idioms in Numpy

In this segment, we examine some of the useful functional programming idioms available in numpy.

10. Using Polynomials in Numpy

In this segment, we examine some of the built-in features for creating, manipulating, and using polynomials in numpy.

11. Understanding and Using Strides in Numpy

In this segment, we explore Numpy strides and show how they can be effectively used to create overlapped arrays.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for unpingco
