2.1.1 Argument Passing

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 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 `-c command` is used, `sys.argv[0]` is set to `'-c'`. Options found after `-c command` are not consumed by the Python interpreter's option processing but left in `sys.argv` for the command to handle.
