Jython is also an option, but you can easily (ctypes, Cython, SWIG, etc.) extend CPython with the exact data models you’d like, e.g. https://pypi.python.org/pypi/bintrees/0.3.0

There is nothing like that in Java. You might want to look into Scala instead. It is Java compatible, has the STL-like programming and even more. When it comes to data structures I do see one weakness in python when compared with Java: you cannot choose your data structure implementation.

In Java when you do something like “SortedMap m = new TreeMap()” you know you are using a tree, which is actually a red-black tree. You can also choose a HashMap and so on. In python you only have one choice, the dictionary. How is python dictionary implemented? I don’t know but it seem to be an open hash table.

If you want to go with JVM, Scala goes one step further, you can choose your data structure implementation, has STL-like programming, supports functional programming, etc. I see it kind of like a fusion between Java and Python and some functional languages. You might want to look into Clojure also, although that’s a functional language.

I know Java very little and I do not know Python ( which I am looking at right now as a free alternative to C# ). I immediatelly feel from where the power of python comes – STL-like programming style on collections. Long ago I have got to work with STL and was totally blown by its incredible power. ( STL is an extension of C++ ). Is there something like that in Java? Which language is going to win eventually? ( Besiges unbreakable C++ place under the sun ) The one which realises STL-like programming. Period.

No matter if you like the examples or not, python is used in large applications, like Dropbox client and all server applications.

Comments are longer than post, then Java is better

If you cannot write proper english, you will have a lot more difficult writing in a formal language like python or java.

Since everyone above is saying that Eclipse saves Java programmers from a lot of these problems, I’ll use the same defense for python. Python has libraries like pyLint and pyChecker that IDEs can use. For instance, in the example above, if you typed fooo=7 the IDE (such as Eric5) would periodically check the code in real time and then flag that line with a warning like “Variable initialized but never used”. Do something like “x = fooo + 3″ and it’ll warn you with “Variable used but never initialized”, etc.

You clearly have not counted in bicycle addicted like me… With which I do not want to state that I would not consider to stretch the application of Phyton a bit to see how far it will go. Or are you suggesting the car being the metaphor for Phyton? Of course in this case the metaphor is a bit off too as we are using Phyton (Django front end) and Java (with rest interfaces) in the same project.

I know that you are aiming to make the code examples comparable, but do you have to use camelCase in Python? The Python conventions call to use underscores for variable and function names, and CamelCase only for class names (and camelCase where the first letter is lowercase nowhere).
