On Thursday Heroku updated its platform-as-a-service (PaaS) cloud to support version 3.3.0 of the Python runtime as well as 2.7.3. 

Python is a popular tool in the modern web developer's arsenal; in January the PyPL Popularity of Programming Language Index named it the second most popular language in the US behind Java, according to Google Trends data

The latest version of the Python runtime differs dramatically from Python 2.7.3 with many commands altered to extend Python's cherished simplicity and brevity. 

But only some developers will be able to get the most out of the latest runtime as many Python libraries are yet to be updated from the second generation, so some developers could struggle to get their code up and running without having to recode libraries to version 3.x

Besides Heroku, Microsoft's Azure and Google's App Engine are capable of running Python applications, though both of these platforms only support version 2.7.3 of the language.

Heroku's biggest rival, Oracle-backed EngineYard, does not support Python.

Python 3.3 was released in September 2012, and 2.7.3 came out back in April.
