Hello, everyone after moving to university from Schools we need some good exposure to the field we are studying. I am studying Computer Applications and I found a good resource to get people started with computer science from the beginning. If the people have taken the introductory course of computer science in college earlier and still do not feel confident about what they have learnt and want to develop themselves. They must do it.
Intro to Computer Science CS101 offered on udacity introduces computer science to the people. The basic stuff like software , hardware and the most important to instruct the computer is the programming language and in this course they have used python 2.7 to introduce the newbees programming and one more benefit is that at the end of the course you would finish up making your own web crawler or web spider written in python. Web crawler is a program search engine like Google uses to find pages and index them according to the page attributes (page rank, most visited pages, max occurrence of the word on the page) of the webpage. So have a look at that I have completed the course and received a nice certificate and I am very happy to share it with everyone.
