jython

I have a list that I need to make into a dictionary. The list has duplicate (soon to be) keys which have different values. How do I find these keys and append the new values to it? list=[q:1,w:2,q:7] dictionary= q:1,7 w:2 Thanks in advance Make the values in your dictionary lists, so that you have: dictionary = {'q': [1, 7], 'w': [2] } etc. ie, your one-item values are one-item lists. This means when you have another 'q' , you can do this: dictionary['q'].append(5) Except that dictionary['q'] will be a KeyError the first time you do it, so use setdefault instead: dictionary.setdefault('q', [])

Edit: In case the multiple tags are confusing, I'm working in Jython. Here's my SSCCE : from javax.swing import JFrame window = JFrame('Test', defaultCloseOperation = JFrame.EXIT_ON_CLOSE, size = (800, 600)) window.visible = True The window opens, sits there for a few seconds, and then closes. So far the only solution I've found is to add while True: pass to the end, which would seem to indicate that the problem is that window is going out of scope, so it gets cleaned up and has to close. This may in fact be another symptom of the same problem I have encountered previously . However, I don't

I am having a tough time getting jython to work properly when run from an Eclipse plugin. I have a simple object factory that loads a python module conforming to a Java Interface. All of this works fine in standalone mode. However, when I package this as an eclipse plugin, I get a different error based on a few variables: Given that my java package is com.foo. 1) If I run without modifying any paths, I get: "No module named foo" 2) If I then add my java jars to the sys.path using: PythonInterpreter interp = new PythonInterpreter(null, new PySystemState()); PySystemState sys = Py.getSystemState

I tried to run HtmlUnit with Jython following this tutorial: http://blog.databigbang.com/web-scraping-ajax-and-javascript-sites/ but it does not work for me. I am unable to import the com.gargoylesoftvare packages, there are only some HTML files in HtmlUnit folder, which I need to import somehow? The tutorial says to run python script like this: /opt/jython/jython -J-classpath "htmlunit-2.8/lib/*" gartner.py and I try to run: java -jar /Users/adam/jython/jython.jar -J-classpath "htmlunit-2.8/lib/*" gartner.py My problem is I am getting an "Unknown option: J-classpath". But there is not even

I'm using Jython from within Java; so I have a Java setup similar to below: String scriptname="com/blah/myscript.py" PythonInterpreter interpreter = new PythonInterpreter(null, new PySystemState()); InputStream is = this.getClass().getClassLoader().getResourceAsStream(scriptname); interpreter.execfile(is); And this will (for instance) run the script below: # myscript.py: import sys if __name__=="__main__": print "hello" print sys.argv How I pass in 'commandline' arguments using this method ? (I want to be able to write my Jython scripts so that I can also run them on the commandline with

According to what I've read, sys.path should be set by PYTHONPATH. In Python, it works that way, but not in Jython. I can circumvent with -Dpython.path=... but I'd like to know why Jython isn't playing nicely. qa@Scantron:/tmp/pip-build-qa/robotframework> echo $PYTHONPATH /usr/lib64/python2.7 qa@Scantron:/tmp/pip-build-qa/robotframework> jython Jython 2.2.1 on java1.7.0_17 Type "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/usr/share/jython/Lib', '__classpath__'] >>> ^D qa@Scantron:/tmp/pip-build-qa/robotframework> jython -Dpython.path=/usr/lib64

In Java, I can say Thread t = new Thread(){ public void run(){ // do stuff } } (or something much like that) to declare an anonymous class inline. This is most useful for making event handlers or other callback sorts of things, that in any sensible language wouldn't require an object to own them in the first place. I face the same problem in Jython -- I want to define an event handler, but I don't want to build a whole standalone class to do so. Ideally, I'd just be able to pass a lambda and be done with it, but if this is possible, I can't find it anywhere in the docs. davidrmcharles Here are

When using MonkeyRunner, every so often I get an error like: 120830 18:39:32.755:S [MainThread] [com.android.chimpchat.adb.AdbChimpDevice] Unable to get variable: display.density 120830 18:39:32.755:S [MainThread] [com.android.chimpchat.adb.AdbChimpDevice]java.net.SocketException: Connection reset From what I've read, sometimes the adb connection goes bad, and you need to reconnect. The only problem is, I'm not able to catch the SocketException . I'll wrap my code like so: try: density = self.device.getProperty('display.density') except: print 'This will never print.' But the exception is
