I prefer Python over Perl because of its legibility (it's way more clear  
than Perl!), expressiveness (there is no big difference between "what I  
want" and "what I write"). (Anyway, I think most people here would say  
they like Python...)

Most database modules implement DBAPI 2.0, the Python standard API for  
database connectivity, see http://www.python.org/dev/peps/pep-0249/
Migrating from one database to another, if you stick to the API, may have  
little or no impact on your application.

The first hit on Google for "python sybase" points to the python-sybase  
project on Sourceforge, which claims to be DBAPI 2 compliant, but I've  
never used it.

If you had some programming experience then Dive into Python  
http://www.diveintopython.org/ would be a good choice

Both, almost zero effort, just run the installer.
