How to upload a file and some data through HTTP multipart in Python 3 using the requests library

Undeniably, the HTTP protocol had become the dominant communication protocol between computers.

For example, when we want to upload a file and some data from to a HTTP server, we do so through a HTTP multipart request.

So how can we do that in Python? In Python 3, we can use the services of the requests library to help us construct HTTP multipart request easily.

In case you need it, this is how to upload a file and some data through HTTP multipart in Python 3 using the requests library.

How to setup Python Imaging Library, Pillow, on Raspbian Stretch Lite for processing images on your Raspberry Pi

When you are building a Raspberry Pi project that deals with images, the Python Imaging Library, Pillow can be very useful. For example, if you connect a camera to your Raspberry Pi 2 or 3 and took a picture, you may want to resize the picture before sending it to a server endpoint.

In case you have trouble setting up Pillow on Raspbian Stretch Lite, this post is for your reference.

Programming languages that you can use to build applications for Raspberry Pi, via Raspbian Stretch Lite

A programming language give programmers an interface to create computer applications to serve different use cases. On the other hand, a Raspberry Pi is one of the things that a programmer should consider getting.

Raspbian Stretch Lite is the official operating system for programmers to run server applications on a Raspberry Pi. You can use Raspbian Stretch Lite for applications that do not require a graphical user interface.

So what programming languages can you use for building applications for Raspbian Stretch Lite?

This post discusses some programming languages that you can use for building applications for Raspbian Stretch Lite.

How to permutate a string in Python 3

To permutate a string is to change the order or arrangement of the characters that the string is made up of. Given that n is the number of characters, there are n! different ways to permutate a given string.

This post shows how we can permutate a string in Python 3.

How to setup Jupyter Notebook on Raspberry Pi 3 with Raspbian Stretch Lite, Supervisor and Virtualenv to run Python 3 codes

By taking Andrew Ng’s Deep Learning Coursera course, you can get a better understanding of deep learning. In addition, you will also get many Jupyter Notebook documents that you can reference to build models that can solve interesting problems.

In order to readily access these documents, you may want to setup Jupyter Notebook on a single board computer like the Raspberry Pi 3. With this in mind, this post shows how you can setup Jupyter Notebook on Raspberry Pi 3 with Raspbian Stretch Lite, Supervisor and Virtualenv to run Python 3 codes.
