I'm trying to get python works in Eclipse with me. I did download Pydev and wrote a small python code.

my python version is: Python 2.7.6 on my Mac OS X 10.9.2

the error I'm receiving now is(BTW I'm getting this error with Jython 2.5.4rc1 and Python interpreters): 

Traceback (most recent call last):

How can I solve it?

只有 python 2.7+ 具有 print_function 未来导入。

如果你升级到Jython 2.7 Beta 2我敢打赌这个问题会得到解决
