How to unpickle a file in Java?

由 旧街凉风 提交于 2021-02-18 19:45:15
问题 I have a 'pickle' format datafile that was created by a Python process (actually, the MCDungeon cache file). I want to read this from a Java program. To do this, I have used this code: public HashMap<String, Object> getDataFileStream(String filename) { HashMap<String, Object> data = new HashMap<String, Object>(); File f = new File(filename); InputStream fs = null; try { fs = new FileInputStream(f); } catch (FileNotFoundException e) { Log.warning("Pickle file '"+filename+"' not found!");

python制作游戏总结

一.序列应用——猜单词游戏 1. 游戏介绍 猜单词游戏就是计筧机随机产生一个单词，打乱字母顺序，供玩家去猜测。此游戏采用控制字符界面 2. 程序设计思路 游戏中，可使用序列中的元组存储所有待猜测的单词。因为猜单词游戏需要随机产生某个待猜测单词以及随机数字，所以引入random模块随机数函数。其中，random.choice()可以从序列中随机选取元素。 在游戏中，随机挑出一个单词word后，把单词word的字母顺序打乱的方法是随机单词字符串中选择一个位置position，把position位置的字母加入乱序后的单词jumble，同时将原单词word中position位置的那个字母删去（通过连接position位置前字符串和其后字符串实现）。通过多次循环就可以产生乱序后的新单词jumble。 3. 游戏结果展示： 4. 代码： import random WORDS=("python","jumble","easy","difficult","answer","continue","phone","position","game") print( """欢迎参加猜单词游戏 把字母组合成一个正确的单词 """ ) iscontinue="y" while iscontinue=="y" or iscontinue=="Y": #从序列中随机挑出一个单词 word=random

Calling jython script from java

问题 I am currently working on a simple hello world program using jython and java. The program is designed in way that a jython method accepts a name parameter and returns welcome message. My problem is whenever I am accessing the jython method from java, it shows nullponter exception My jython Script (JythonHello.py): class JythonHello: def __init__(self, name): self.name = name def sayHello(self): return "Hello "+ self.name and my java code: public static void main(String[] args) {

I am using the following command as specified on JyNI.org: java -cp /home/ch/jython.jar:/home

How can I install Python libraries using Jython Standalone in Java?

由 江枫思渺然 提交于 2021-02-07 07:26:24
问题 I am trying to install Python libraries using a Jython Standalone jar in Java. The code I have seems to install PIP 7.1.2 in a folder next to the standalone jar, but once I try to use PIP to upgrade itself, it fails with a ZipImportError. The error message seems to complain about not being able to open the PIP wheel file, but the log seems to show it being able to open it a few times already. import org.python.util.PythonInterpreter; public class PipInstaller{ public void installPip(){

问题 I'm trying to write a script to test all DataSources of a WebSphere Cell/Node/Cluster. While this is possible from the Admin Console a script is better for certain audiences. So I found the following article from IBM https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.multiplatform.doc/ae/txml_testconnection.html which looks promising as it describles exactly what I need. After having a basic script like: ds_ids = AdminConfig.list("DataSource").splitlines() for ds

BurpSuite插件开发指南之 Python 篇

此文接着 《BurpSuite插件开发指南之 Java 篇》 。在此篇中将会介绍如何使用 Python编程语言 开发 BurpSuite 的插件。 《BurpSuite 插件开发指南》系列文章如下： 《BurpSuite插件开发指南之 API 篇》 《BurpSuite插件开发指南之 Java 篇》 《BurpSuite插件开发指南之 Python 篇》 注：此系列文章是笔者利用业余时间所写，如有错误，望读者们及时指正，另外此系列文章属于入门级别的科普文，目的是普及Burp插件的编写技术。 0x00 Jython 简介 BurpSuite 是使用 Java 编程语言编写的，所以想要使用 Python 编程语言开发其插件，就必须借助于 Jython。Jython 本质上是一个 Java 应用程序，它允许 coder 们使用 Java 代码调用 Python 库反之，也可以使用 Python 调用 Java 的库。 有关 Jython 的详细使用，请读者参阅 Jython 官网的用户手册 和 相关 doc。 类似于 Jython 的 Project 还有 JRuby ，并且 Burp 也支持 ruby 编写插件，但是无论是用 Python 还是 Ruby 编写的插件，在执行效率方面远远不如原生的 Java 高，所以笔者还是建议使用 Java 编写插件。 0x01 Python 编写

jython multithreading

问题 I started studying python a couple of month ago, then I found Jython. Do threads work properly in Jython, since it doesn't have a GIL? If so, can you suggest a good book on concurrency (threading)? 回答1: The best book I've encountered on multithreading is "Java Concurrency in Practice". It's very much concentrating on Java thread concurrency, and is both humbling and exciting when you start to understand the problems and the possibilities introduced by concurrency. The copy I bought a few
