pyjamas

It allows writing web applications in Python, which is more suitable performance-wise for medium to large applications.

The AJAX library takes care of all the browser interoperability issues on your behalf, leaving you free to focus on application development instead of learning all the "usual" browser incompatibilities.

Key features "Pyjamas":

· pyjs - translates Python code to Javascript by walking the Python abstract syntax tree and generating Javascript.
· pyjslib - library of custom objects that implement methods such as append
· UI widgets as well as a library for DOM manipulation
· The overall translation of individual components is managed by build which also creates the necessary boilerplate code.

What's New in This Release:

· Significant bugs fixed include HorizontalPanel's remove() function, SimplePanel's clear() function, and sprintf with multiple arguments ("%s %d" % ("hello", 2) will now work)
· Dialog Box now has modal functionality
· HorizontalSplitPanel has been added, although both the horizontal and vertical panels operate correctly on Mozilla-based browsers, but Safari and IE need volunteers to work on them.
