need help regarding compilation
i am new to learning jython... i just tried compiling a small piece of code that is given below: def fac(x) if x<=1:return 1 return x*fac(x-1) on C:\Program Files\jython\temp>jythonc factor.py it showed the following error: processing factor Traceback (innermost last): File "C:\Program Files\jython\Tools\jythonc\jythonc.py", line 5, in ? File "C:\Program Files\jython\Tools\jythonc\main.py", line 298, in main File "C:\Program Files\jython\Tools\jythonc\main.py", line 219, in doCompile File "C:\Program Files\jython\Tools\jythonc\compile.py", line 195, in compilef ile File "C:\Program Files\jython\Tools\jythonc\compile.py", line 209, in compile File "C:\Program Files\jython\Tools\jythonc\SrcGenCompiler.py", line 1079, in execstring File "", line 1 def fac(x) ^ SyntaxError: invalid syntax What may have gone wrong? I am totally clueless as it is not mentioned in any of the books that I tried. -- http://mail.python.org/mailman/listinfo/python-list

Would be really thankful if someone could tell me as to what is going wrong. processing factor Required packages: Creating adapters: Creating .java files: factor module Compiling .java to .class...

> You really have a book about python that doesn't mention that functions > definitions are closed by a colon? I doubt that... It is not python but jython. But I dont think that the syntax of both of them are different. I managed to download the tutorial of jython from the IBM website. I am wondering as to how they could put in wrong syntaxes in their tutorials !! -- http://mail.python.org/mailman/listinfo/python-list

But why is it throwing a compilation error in my case here? -- http://mail.python.org/mailman/listinfo/python-list
