Can Django give same functionality as my current Drupal sites?

Im building website in Drupal, which have:

Feed aggregator

-Aggregate feeds and mapping to categories, tags

Ping

-Ping new contents to search 开发者_JS百科engines, Ping-o-matic, etc.

Workflow

-When contents is viewed, publish to front page

-When contents published to front page, send ping to search engines, Ping-o-matic, etc.

Import HTML static files from old website

-Import to specific category, to specific content types

Can Django doing this?
