When does running Jython on a .py file generate a .class file?

Question

I just started playing with Jython, and sometimes running jython on a .py file generates a .class file, but this doesn't always happen.

At first I thought the trigger was that you had to define a Python class inside the .py file, but evidently a .class file is not always generated even then.

What is the mechanism that triggers the class file?

Thanks.

It doesn't look like that's the case -- there are several import statements in there. — espeed, Aug 21 '11 at 00:33
Oh, ok. Evidently that does generate the .class file. Thank you. — espeed, Aug 21 '11 at 00:53

With regular Python, .pyc files are generated when you import a module but not when it's the __main__ module.

It is the same with Jython -- .class files are generated when you import a Jython module.

You can use jythonc to manually compile a module.

There is no jythonc in Jython 2.5 though. – mzjn Aug 22 '11 at 19:30
