Differentiating Scala and Python based on Advanced Features. 4. Activity. But, as Spark is natively written in Scala, I was expecting my code to run faster in the Scala than the Python version for obvious reasons. Both the language itself and its community have made it quite clear that you should do everything the "Pythonic way" to get the best results, that it feels more like an opinionated framework instead of a general-purpose programming language, which means if you are a first-time learner and getting too "tuned" to the "Pythonic way" it will be much harder for you to learn other less-opinionated languages compared to the other way around. You might never look at the conventions. Add to Chrome Try it now. Python is not limited to just be cross platform. Scala and Python have different advantages for different projects.
