Set the new password and then run: To ensure we will be installing the latest packages run the following two commands: Install pip Before we can install Flask we need to install pip, the Python package manager: Create test Flask app Now that Flask is installed we need to create a small test site to check everything is working.

Create a new folder: This script defines a simple one page website. Testing the Python web server You can now run the script using: Note that Flask uses port by default and you need to replace Take a look at the example below: This page will be displayed when you visit the hello sub-directory: Even more routes You can also pull information from the URL into your script to create more elaborate page combinations.

This makes the script much easier to handle when your pages are a bit more complicated. Create a new directory for templates: So the visitor sees a slightly different page. The great thing with templates is that they keep the main Python script focused on functionality and leave the layout and aesthetics to the template file.

This runs Flask in debug mode which automatically reloads Flask when you update the script.

Most HTTP servers are written in C or C++, so they cannot execute Python code directly – a bridge is needed between the server and the program.

These bridges, or rather interfaces, define how programs interact. A WebSocket server can be written in any server-side programming language that is capable of Berkeley sockets, such as C(++) or Python or even PHP and server-side JavaScript.

This is not a tutorial in any specific language, but serves as a guide to facilitate writing your own server.
