Basic Web Server (On the fly Creation)

Hello World,

Many times specially during web development on core HTML 5[although its not just limited here only.], we need a web server to test the application and specially JavaScript and other features of html 5, which are only available on localhost,HTTP.

 Now, here you can go with traditional web servers like Tomcat Apache or any other server, but then you need to configure them accordingly and very carefully and that may took very dedicated time around 00:30 mins to 1 hour [i am talking here about very basic web server].

 So, is there any techniques that can help us to creating a web server in just a simple one line command hit... Yes there is. actually there are many server framework that are just a few line setup away to have a basic web server.

 Here i gonna talk very simplest one, that will help us to create a very basic web server. And it is Python's module "SimpleHTTPServer".

 Dependency/Requirement: But there is a very small dependency to have you on your system where you want your server. and its PYTHON-2.7 that's it, nothing else.

 if you don't have python-2.7 installed on your system, then just go here and install the python-2.7 right now, and if you have already having python-2.7 installed on your system, then just hit the following command

Command / Demo:
Syntex (for python2): >>> python -m SimpleHTTPServer
Syntex (for python3): >>> python -m http.server

E.g.(Python2):     >>> python -m SimpleHTTPServer 8900
E.g.(Python3):     >>> python -m http.server 8900
                   Serving HTTP on 0.0.0.0 port 8900 ...



The reason, its showing the directory listing because we do not have any index.htm/l file here. Just simply put your index.htm/l file to start serving your web application directly without showing the listing.

So from here, one thing is also concluded that you can share any file[txt, json, media, etc] with public.



Things you have to Notice here are:

 1# The location of current working directory would be public after hitting this command. So just by changing the current directory location you can easily change the public folder to be served by this HTTP sever.

 2# PORT_NUMBER. [0-1023] are system reserved ports. So don's use these ports. you may use port number greater than 1024 and less than 65565, if that port would be available then it would start a HTTP server on that port.

Print emojis using python (😀, 👍, ...)

Image
Hello World, Everyone of us usage the emojis at some point, because its quiet expressive. and when you are a programmer then it becomes more curious to print emoji characters out. I thought of printing emojis out for the logs , most of the time when I used to print the logs specially for the errors or exception message then I always try to express the message with more expression .  Well, you can print emojis using python as well. For that we can follow one of the following things: 1- Unicodes 2- Library 1- Unicodes: There are unicodes for every single character that is going to be printed out and that's why there are unicodes for the emojis too. For example : Unicode for thumbs up is "U+1F44D" which in python is going be be as "U0001F44D". As you have noticed that we are replacing "+" with "000", and not only that we also append "\" in front of this unicode while printing. So finally the thumb up emoji can be printed with : print(...

Scraping with Python

Hello World, There is more information on the Internet than any human can absorb in a lifetime. What you need is not access to that information, but a scalable way to collect, organize, and analyze it.  Then, You need web scraping.   So let's discuss this scrapping thing. Now, the Scrap Means: to take out something from somewhere and If we add 'web' to it, then it means to take out something from the web resources.  Web scraping automatically extracts data and presents it in a format you can easily make sense of. In this tutorial, we’ll focus on its applications in the webpage data extraction, but web scraping can be used in a wide variety of situations. Roadmap for this blog: - Setup with the tools and library - Basic of the HTML DOM - Scrapping Rule - Coding part Pre-Requisite: - A basic understanding of programming concept in python ---------------------------------------------------------- Getting Started with the tool...
