Re: Use Python libs or Java libs

I am afraid I have some bad news for you.

Jython CANNOT use python libraries.

Of course there ways that jython could use python libraries . Two come in mind this moment:

a) Use a python library that uses pure python with no C/C++ wrappings. I am afraid that is very rare in python libraries

b) Use C/C++ wrapped python libraries ported to Java through JNI. Very rare to do or find.

So as a general rule you are forced to use in 99% of cases Java libraries with jython, and python libraries with python.  

Why choose python instead of java libraries ? Well because python libraries are much more "pythonic" thus easier to use and understand. However using jython makes it easy to jump from jython to python as the diffirences between the two languages are minimal.

So in the end , jython is a very useful for java developer who want some of the ease of use of python , or for python programmers that want access to myriads of Java libraries out there.  If you want to use both , Java and python libraries , then your porgramm should be made in both languages Jython and Python and make a way for the two to communicate with each other.

Hi list,This is probably a common question, but I figured I'd ask again.
There is a certain amount of overlap between the Java libraries and Python
libraries, so when using Jython, when does one know which to use?
For example, both have os and sys libs, that have similar functionality.
How does one decide?

Thanks.
