Sorry to ressurect the thread, but there was no accepted answer… You could also use Py4J. There is an example on the frontpage and lots of documentation, but essentially, you just call Java methods from your python code as if they were python methods: >>> from py4j.java_gateway import JavaGateway >>> gateway = JavaGateway() # connect … Read more
Some Python modules, like lxml, have required components in C. These won’t work in Jython. Most Python packages will work fine, and you can install them using the same tools as you use in CPython. This is described in Appendix A of Jython Book: To get setuptools, download ez_setup.py from http://peak.telecommunity.com/dist/ez_setup.py. Then, go to the … Read more
I recently went down this path as well; though it sounds like my application was slightly different. I was interested in approximating set operations on a large number of strings. You do make the key observation that a fast bit vector is required. Depending on what you want to put in your bloom filter, you … Read more
The best current techniques for distributing your Python files in a jar are detailed in this article on Jython’s wiki: http://wiki.python.org/jython/JythonFaq/DistributingJythonScripts 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, … Read more
You can use psutil (https://github.com/giampaolo/psutil), which works on Windows and UNIX: import psutil PROCNAME = “python.exe” for proc in psutil.process_iter(): if proc.name() == PROCNAME: print(proc) On my machine it prints: <psutil.Process(pid=3881, name=”python.exe”) at 140192133873040> EDIT 2017-04-27 – here’s a more advanced utility function which checks the name against processes’ name(), cmdline() and exe(): import os … Read more
I’m aware of the Jython project, but it looks like this represents a way to use Java and its libraries from within Python, rather than the other way round – am I wrong about this? Yes, you are wrong. You can either call a command line interpreter to run python code using Jyton or use … Read more
Use %d in your PatternLayout. Also %d can take a format pattern as in %d{dd MMM yyyy HH:mm:ss,SSS} you can pick and choose the elements that you want. When the format pattern is omitted the date will be in ISO8601 format.
Jython doesn’t compile to “pure java”, it compiles to java bytecode – ie, to *.class files. To develop for Android, one further compiles java bytecode to Dalvik bytecode. This means that, yes, Jython can let you use Python for developing Android, subject to you getting it to play nice with the Android SDK (I haven’t … Read more
Another update: an August 2020 commit clarified that the repository to look at is not the Jython3 one but the main Jython repo. Anyway “The latest version of Jython remains 2.7.x. A Jython 3.x should appear, but exploratory work towards it is not stable at the time of writing. Please watch the jython-dev mailing list … Read more
If you want to determine whether a value is exactly True (not just a true-like value), is there any reason to use if foo == True rather than if foo is True? If you want to make sure that foo really is a boolean and of value True, use the is operator. Otherwise, if the … Read more
