我尝试了Jython 2.2.1版本，没关系，但问题仍然存在于Jython 2.7b1版本中：

Answer 1

我试过这个，我的版本效果很好：

Jython 2.5.3 (2.5:c56500f08d34+, Aug 13 2012, 14:48:36)
[Java HotSpot(TM) Client VM (Oracle Corporation)] on java1.7.0_09

我使用Jython和Java的更新版本，但我认为这不是问题。尝试在print文件中保存这些print_test.py语句，并通过jython print_test.py和CPython python print_test.py执行。向我们展示结果。

Answer 2

同样的问题：

Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_02

>>> print 'hi'
...

看起来只是2.5.2的错误

也许这是特定于操作系统或机器环境，因为它在2.7.0的Windows上表现得很好，并且已经看到它在以前的版本中运行。
