Hello, I am vegaseat, the goofy moderator from the Python forum of DaniWeb. I wanted to know if anyone in the Java forum has played around with Java based Python, also known as Jython.
Jython uses easy to learn Python syntax and can use the Java libraries. To make a short story long, here is an example ...
""" jy_List_99BoB2.py
create the full lyrics of the '99 bottle of beer' song
and show in a Jython (Java based Python) scrollable list box
Download file jython_installer-2.5.2.jar
from http://www.jython.org/downloads.html
On Windows just double click the .jar file
and Java will install the Jython program
into a directory called jython2.5.2
to this .py file on Windows use:
Jython.bat jy_List_99BoB2.py
tested with jython2.5.2 by vegaseat

# allows frame corner x to exit properly
frame.defaultCloseOperation = JFrame.EXIT_ON_CLOSE
frame.setLocation(100, 150)
frame.size = (400, 300)
# create a list box and load it with the lyrics
swing_list = JList(list_99bob)
# give it a little color
swing_list.background = Color.yellow
# make it scrollable
swing_list_scroll = JScrollPane(swing_list)
frame.add(swing_list_scroll)
frame.visible = TrueIf you have any Jython code samples, you are invited to the Python forum for an informal posting.
Oh, I almost forgot, Python and therefore Jython are OOP languages and you can write your code in OOP style of course. For simple stuff I usually don't.
