(instead of saying "google is your bud", & because this ? isn't readily FAQ-able)
i suggest Google Advanced Searching c.l.py for "python IDE intellisense" or "code completion" or "regex debugger" or "contextual help" or "whatever_feature" (each feature has about 15 codenames, keep at it), maybe throw in your O/S of choice. 2005 threads have volumes written about vim,emacs,eclipse, eric, komodo, wing, Jedit, SPE, KDevelop, others. Then send feedback to the wiki: http://wiki.python.org/moin/IntegratedDevelopmentEnvironments (oh, and don't expect a perfect Visual Studio/IntelliJ/eclipse for java workalike) -- http://mail.python.org/mailman/listinfo/python-list
