comunque nell'html della pagina web in questione si legge:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

ho provato a mettere allora:
#!/usr/bin/python
#-*- coding: iso-8859-1 -*-

ma, all'atto di salvare il file per poi eseguirlo, esce questo:

These default coding systems were tried to encode text
  (iso-latin-1-unix (293 . 8212) (298 . 8217) (303 . 8221) (308
  . 8220) (1067 . 8220) (1088 . 8221) (1109 . 8212) (1130 . 8217)
  (2227 . 8220) (2279 . 8220) (2360 . 8221))
However, each of them encountered characters it couldn't encode:
  iso-latin-1-unix cannot encode these: — ’ ” “ “ ” — ’ “ “ ...

Click on a character (or switch to this window by `C-x o'
and select the characters by RET) to jump to the place it appears,
where `C-u C-x =' will give information about it.
Select one of the safe coding systems listed below,
or cancel the writing with C-g and edit the buffer
   to remove or modify the problematic characters,
|or specify any other coding system (and risk losing
   the problematic characters).
