What?

This is a Python 3 HTTP/1.1 server bound to 127.0.0.1 on port 8000 using only the standard library.

Why?

I wanted a simple Python 3 web server using HTTP 1.1 that can perform simple HTTP operations and depends only on Python and standard library modules. I couldn't find an example so I made one.

The example demonstrates how to accept different methods, parse the url and query strings, read data sent to the server, parse and return json, return responses with different status codes and headers, handle graceful termination, and override the default error logging.

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.
