There some things that made me conclude that Java is easier than python
1) Good documentation. Yes python has a very simple syntax , while java is more verbose but nothing can make thing any easier than good documentation, especially with third party libraries. Many of them actually require their users to read C++ documentation that defeats the purpose of using python in the first place.
2) Speed. Python is very slow, and even this does not show very often only for CPU intense tasks , that does not mean that python does not consume too much CPU. Again this might not be the problem for non intense CPU stuff, but because I working with midi and audio it makes my life harder.
3) Lack of a good IDE, IDEs is an essential part of RAD and none of the IDEs that support python works in a way that is hassle free. Especially in the GUI design department these IDEs leave alot to be desired.
I love the python syntax, it is surely the best of the best, that is why I have jython close at hand , but overall, at least for me what killed python is bad documentation and fragmented cross platform availability of libraries ( I have even experienced severe problems into making python work on macos).
I dont see python conquering the universe, the best language is yet to be invented. Its a great language however and alot of fun to use.
I do understand that the 3 above may not apply in all cases. Some people do not use IDEs, their python libraries have very good documentation, and do not real need speed.
My issue with python are quite old, but it was now that I decided to make an app that via MIDI protocol will control external hardware synthesizers ( I make music as well -> www.soundclick.com/kilon ) . Problem one , finding the right GUI. Qt is not free, GTK need X11 to work in mac, and Wxpython has non existent official documentation. Problem two, finding the right MIDI library, again the documentation is non existent.
Also I did not like the pure python ides or the IDEs that support python via plugin. I ended up that I would had to use several programm to do what I want and that is not good.
Java already solved the above problems.
Another motivation is jython. Java developers hate it beacause it inherits the slowness of python. Python developers hate it because it does nto allow of the use of cpython libraries unless they are already implemented in jython and thus is tied to java library and thus is not really pythonic. And other people love it ,like me, because it unites easy python syntac with the power and popularity of java libraries.
