问题 My final purpose is to convert a running Python project to Jython interpreter because some java API's are going to be added. Details: The latest Jython is 2.7 The project I have is runnable with Python 3.5 So I took the following approach: First thing was to convert my project to Python 2.7 utilizing the future module and pasteurize executable. This step was done successfully. Second thing is to convert the Python 2.7 project to a Jython 2.7 Project. Switching the interpreter at Eclipse mars,

问题 I wrote a Java example, the code is: import org.python.core.PyObject; import org.python.util.PythonInterpreter; import javax.script.ScriptEngine; import javax.script.ScriptEngineFactory; import javax.script.ScriptEngineManager; import javax.script.ScriptException; import java.util.List; class JythonExample { public static void main(String args[]) throws ScriptException { listEngines(); ScriptEngineManager mgr = new ScriptEngineManager(); ScriptEngine pyEngine = mgr.getEngineByName("python");

问题 I have a few projects which run using Jython 2.7b1 where I add the jars (in fact all the jars in a directory) by doing this: set CLASSPATH=.;"%SYSADMIN%\resources\java jar files/*" set JYTHONPATH=... C:\jython2.7b1\jython myproj\__main__.py But my latest project is using 2.7.0FR and this "set CLASSPATH" approach doesn't seem to work. I then tried this: D:\apps\jython2.7.0\bin\jython -Dpython.path="%SYSADMIN%\resources\java jar files/*" my_latest_proj\__main__.py ... but it didn't work. Then I

问题 I am trying to experiment with java 8 streams and collections in jython to see if they are any efficient then when implemented in pure jython. It occurs to me it could (any comments on this also appreciated) I started with some examples, the counting from java.util.function import Function from java.util import ArrayList from java.util.stream import Collectors letters = ArrayList(['a','b','a','c']); cnt=letters.stream().collect(Collectors.groupingBy(Function.identity(), Collectors.counting())

问题 Jython is an implementaion of python. Is there any way to find the version of python that is being supported by a particular jython jar. eg: Few posts in the web say that Jython 2.5 supports python 2.5 Similarly I want to know the jython version that supports python 2.7.14 or more. It would be helpful if the version mapping can be referred to in any user-guides or pages. 来源： https://stackoverflow.com/questions/50965533/jython-to-python-version-mapping

问题 I'm trying to use Jython to integrate a small Python script into a Java program I have. I can't seem to get the python/jython engine using the javax.script package.

问题 I am trying to embed Jython in Java because I need to be able to reuse some python code that is parsing a yaml.
