The documentation for urlopen <http://docs.python.org/lib/module-urllib2.html> says that info() returns a dictionary-like object. Try using keys() to see the available keys: among others, you should see 'last-modified' (for objects that provide it; it's not a mandatory header). The 'name' argument is precisely that: the name of the header you want parsed as a date. > Am I going down the wrong path? Is there a path I can go down to get > what I want? In short, you want finfo.getdate('last-modified') -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
