The urllib module's URLopener class does support this feature, albeit
not as part of the standard urlopen function.  If you create an
instance of URLopener (or FancyURLopener), you can use its addheader
method to add headers and then call its open method:
    
    fuo.addheader('Accept', 'sound/basic')
    fuo.open('http://funkymusak.com/sound')

urllib2 does not currently support this in any useful way, although it
would be possible to append to the addheaders attribute of an
OpenerDirector.
