Hi Everyone, I finished the second exercise for python couple days back. There some things that I found different about python. One of them is that variables don’t need to be specified. For example if you are thinking of declaring a string or integer variable you don’t need to specify the word string or int before the variable.

This week we started looking at symbolic links and some commands. One of them is GREP. It stands for globally find regular expression. It searches for a word present in a file. The file name must be specified. We were also introduced to the VI text editor. This week we need to deal with standard input and standard output. We also need to throw a standard error. I need to look at some tutorials which would assist me in dealing with standard input and output.
