gets the parameter flag for a-N and the number that follows it, and then prints only the number of rows in that number size. Each parameter of the Python script is provided through the SYS.ARGV array, which can be accessed later in the import sys. The following code shows how to use a single word as a parameter.

Using a mutable type (like a list or dictionary) as a default argument and then modifying that argument can leads to Strang E results. It's usually best to avoid using mutable default arguments:to see why, try the following code locally.Consider this function which the adds items to a todo list.
