According to the Pyjamas website, many people, when discovering Google Web Toolkit wonder why they can’t use Python instead of Java.
With Pyjamas, this is now possible.
Similar to GWT, a Java software development framework, Pyjamas is a cross-browser Web App development API that allows you to write your client side functionality in Python instead of Java.
While it looks like a desktop API, Pyjamas is a stand alone Python to JavaScript compiler, an AJAX framework / library and a comprehensive widget set API.
The advantage of using Pyjamas is that you can write Web applications in Python instead of HTML and JavaScript; rather than trying to fit as much HTML as you can into one page, you can reuse and import classes and modules.
Additionally, the AJAX library deals with the entire browser interoperability issue – you don’t need to worry about the browser wars to make your app cross browser compatible for IE6, IE7, Firefox, Safari, Opera etc.
