| From the docs@ mailing list: “Tutorial 2.1.1: name 'sys' is not defined When the student tells python to evaluate sys.argv[0] as described, she gets the following error: name 'sys' is not defined” Imports have not been introduced yet, so I propose this simple change: -left in ``sys.argv`` for the command or module to handle. +left in ``sys.argv`` for the command or module to handle. You need to +execute ``import sys`` before you can reference ``sys.argv``. I’m not committing directly because I’d like feedback: Is the wording okay for the beginning of the tutorial? |

| What about "In order to use ``sys.argv`` you have to import the :mod:`sys` module doing ``import sys``.". "reference" sounds weird to me, and imho saying "import the module" is ok even if imports have not been introduced yet. If the user doesn't understand what "importing a module" means he can just execute the command as is. |

| New wording: When known to the interpreter, the script name and additional arguments thereafter are passed to the script in the variable ``sys.argv``, which is a -list of strings. Its length is at least one; when no script and no arguments +list of strings. You have to execute ``import sys`` before you can use that +list. Its length is at least one; when no script and no arguments are given, ``sys.argv[0]`` is an empty string. When the script name is given as ``'-'`` (meaning standard input), ``sys.argv[0]`` is set to ``'-'``. When :option:`-c` *command* is used, ``sys.argv[0]`` is set to ``'-c'``. When |

| "Use that list" doesn't make me happy, what about "access"? |

| Attached diff provides another suggested rewording that I think is clearer. |
