Google App Engine — Java or Python? [closed]

Question

I noticed that this was asked in the following post. Has anyone used both and can conclusively tell me which is better? It seems like python might be a little easier to implement and faster?

Answer 1

I use Groovy (Grails) with GAE. It has Java's library universe and you should have roughly the same LOC compared to Python. Yeah, its not 100% Java (if you want to), but very close. The BIG difference is roughly the JavaVM speed, that's one of the reasons Groovy (Grails) has gained so much popularity - especially people like my who dislike Python .)

Answer 2

.py chosen here for all gae projects for reasons more readable, less lines code, higher level same time java has more ways to solve a given problem. Approx estimate same function with python is 1/10 the code compared to java.

Answer 3

Python ( subjectively speaking )

Answer 4

i use python, becouse always can get the best of django in appengine

Answer 5

By this time, both implementations are reasonably mature and solid, and their functionality is pretty similar (I don't think it's quite 100% equal yet, but, moving in that direction). So, if you already know only one of the two languages, I'd say "just go for it". If you already know both, you don't need my advice;-).

If you know neither, but are rarin' to try some of the non-Java languages that are (more or less;-) supported on the JVM side of GAE (I believe this includes Scala, server-side Javascript, JRuby, etc), then it's worth trying. If you know neither, and don't want to risk a "not-first-class-supported language", I'd definitely agree with your observation that Python's faster to learn (but of course I'm biased in favor of Python;-).

Answer 6

It maybe possible to use Jython in appengine so you could use both. One thing I would say about the python productivity vs Java productivity argument is Java has excellent IDE's to speed up development where as Python is really lacking in this area because of its dynamic nature. So even though I prefer to use Python as a language, I don't believe it gives quite the productivity boost compared to Java when using a new framework. Also I have as yet not been able to get the python version of google app engine to work in Netbeans which is a royal pain.
