If you want to directly import the argv variable into your program (to
		avoid typing the sys. everytime for it), then you can use the
		from sys import argv statement. If you want to import all the names
		used in the sys module, then you can use the
		from sys import * statement. This works for any module. In general,
		avoid using the from..import statement and use the
		import statement instead since your program will be much more readable
		and will avoid any name clashes that way.
