Comments in Python

Line Comments

Line comments in Python are very simple. The # character denotes that everything afterward on that line is a comment.

Block Comments

Unfortunately, there is no specific syntax for block comments in python. To comment a block of code, you must simply place a # before every line in the block of code you wish to comment. Many Python IDE's, however, provide a simple way to comment out a block of code. A tricky way of quickly block-commenting a large block of code is to prefix the block with if False: and then indent the block to be commented. Just remember un-indent and delete the conditional afterward!

» A Brief Introduction to Grep

One of the most useful features of operating from a linux terminal is being able to easily perform functions like grep, which searches a group of files for a matching string. It can return lines with the matching expression, lines without the matching expression, the number of lines matched, and more. This will serve as a basic tutorial and should cover most usage models; grep is an extremely powerful tool. Consult the grep manual for a much more detailed description....
