Is there anything like ASP.NET for Python web apps ?

[Ravi Teja]

If what you want is a web IDE that supports visual development, no
standalone Python IDE has such support. But you can use Python in IDEs
that do support these features.

1.) ActiveGrid (http://www.activegrid.com/) - closest visual web IDE
where Python is a first class member.
2.) Use ASP.NET with Boo or IronPython. Not seamless IDE-wise.
3.) Wait for Coyote to finish (https://coyote.dev.java.net/). It is
still J2EE but you get to use Python. Netbeans, unlike JDev does not
have data bound widgets available.
