Comments ( # )
First thing’s first: Although Python is one of the easiest languages to read, it does not preclude the programmer from proper and adequate usage and placement of comments in the code. Like many of its Unix scripting brethren, Python comment statements begin with the pound sign or hash symbol (#). A comment can begin anywhere on a line. All characters following the # to the end of the line are ignored by the interpreter. Use them wisely and judiciously.
