Does jython depend on java class.

[angel]

Thank you for your reply.

But I still want to confirm if jython requires standard java class, for
example java.lang.* java.util.* ...
>From the word "the python dictionary type is implemented by the java
classes org.python.core.PyStringMap and org.python.core.PyDictionary" , I
guess jython should depend on java.lang.String, java.util.Hashtable ...

So jython doesn't only compile python source code to java bytecode, it is
implemented by java language. Is it correct?

Thanx
