I happen to know the original creator of nbPython (what led to the official Python support in Netbeans), and he's currently on sabbatical from Python as an employed Rubyist. I can put you in contact with him if you want, but I don't know what his level of commitment is to Netbeans post-Oracle. The guy who backed it at Sun/Netbeans, Tor Norbye, also quit after the Oracle acquisition and now works with Google. Unfortunately, I don't see community support keeping it afloat. I'd look at PyCharm since it appears to have a future.
