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.

The prevalence of javascript is so high, and the disillusionment so entrenched, that when something this significant comes along that takes away all the pain of developing comprehensive web applications, not only is there a high signal-to-noise ratio to overcome but also it takes a long, long time for it to sink in to people's minds that yes, web development doesn't have to be as mind-blowingly painful as it's been for the last decade.

Even as the de-facto lead developer, it was a year before i got fed up with CSS / HTML / Javascript manual programming before i initially started using pyjamas, and it was several months before the "squishy" feeling went away, whenever running a build of the python source to turn it into javascript.

so.

yes.

java != javascript - we know!!!

however with GWT, java ==> gets_built_and_turned_into ==> javascript

likewise, python != javascript - we know!!

however, with Pyjamas, python ==> gets_built_and_turned_into ==> javascript.

similarly with RubyJS and its associated (independent) library, rwt, which is an up-and-coming port of GWT to Ruby.
