from wt.query import *
 
QuerySpec qs = new QuerySpec(WTPart.class);
qs.appendWhere(VersionControlHelper
    .getSearchCondition(WTPart.class, true));

if (a) {
    doA();
}
else if (b) {
    doB();
}
else{
    doElse();
}
 
if (a): 
    doA()
elif (b): 
    doB()
else:
    doElse()
 
for (String str : list) {
    System.out.println(str)
}
 
for item in list:

Command Line Tricks

Start Jython
 
jython
Inspect Interp­era­tively after running script
 
jython -i my_scr­ipt.py
Run command
 
jython -c 'print "Hello, World!"'

Interp­reter Tricks

Underbar "­_" can be used to reuse the last result returned
 
>>>qr.nextElement()
...wt.part.WTPart:12345
>>> part = _
You can save a method as a variable in Jython
 
>>> save = PersistenceHelper.manager.save
>>> save(part)
