Jython, successor of JPython, is an implementation of the Python programming language written in Java. As for what uses it may have: Jython programs can seamlessly import and use any Java class. Except for some standard modules, Jython programs use Java classes instead of …

2012年6月12日 · Jython is a java implementation, Cython is C implementation and IronPython is c# implementation. As far as Python language syntax is concerned, it remains consistent in all implementations. Regarding the last part of your question, I dont think Jython version 3.x is released or in use yet, probably you meant python 3.x - if so, yes it is.

2016年6月5日 · Jython FAQ: Jython is an implementation of the Python language for the Java platform. Jython 2.7 implements the same language as CPython 2.7, and nearly all of the Core Python standard library modules. (CPython is the C implementation of the Python language.) Writing Jython is similar to writing standard Python.

2016年3月1日 · I'm also interested in running Python code directly within Java, using Jython, and avoiding the need for an installed Python interpreter. The article, 'Embedding Jython in Java Applications' explains how to reference an external *.py Python script, and pass it argument parameters, no installed Python interpreter necessary:

Jython is an implementation of the Python language for the Java platform. Jython 2.5 implements the same language as CPython 2.5, and nearly all of the Core Python standard library modules. (CPython is the C implementation of the Python language.) Jython 2.5 uses the same regression test suite as CPython, with some minor modifications.

In the final release of Jython 2.7.0, the Jython installer by default runs jython -m ensurepip as the last install step for the standard install. It can also be selected for most of the other types of installs as well. Or run it after install. –

2020年1月30日 · For your case, I think you would want to take the jython.jar file that you get when you install Jython and zip the Jython Lib directory into it, then zip your .py files in, and then add a __run__.py file with your startup logic (this file is treated specially by Jython and will be the file executed when you call the jar with "java -jar").

2015年11月26日 · These would have to be ported to Java, or implemented with a JNI bridge in order to be used by Jython. Some built-in modules have been ported to JPython, most notably cStringIO, cPickle, struct, and binascii. It is unlikely that JNI modules will be included in Jython proper though. If you want to use a standard Python module, just try importing it.

2016年3月25日 · If you really have to use Jython and pandas together and you could not find another way to solve the issue, then I suggest using them in different processes. A Java process is your Jython application running on JVM (either is Java code calling Jython libraries, or a Python code that possibly requires integration with some Java libraries), and ...

2012年6月26日 · In python it works perfectly, but in Jython there is a delay when the function is called which makes it appear that the sleep is being called first. If I increased the wait time to 5 seconds, there is a short delay, then "started" is printed, then the 5 second wait, then "stopped".
