jython 2.5无法打印字符串 [英] jython 2.5 can't print string

问题描述

Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_20
Type "help", "copyright", "credits" or "license" for more information.
>>> print 3
3
>>> print "3"
...

我尝试了Jython 2.2.1版，没关系，但是问题仍然存在于Jython 2.7b1版中:

Jython 2.7b1 (default:ac42d59644e9, Feb 9 2013, 15:24:52)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_39
Type "help", "copyright", "credits" or "license" for more information.
>>> print 'ab'
...

解决方案

也许这是特定于OS或计算机环境的，因为它在2.7.0中的Windows上对我有效，并且在以前的版本中已看到.

什么是基础操作系统，如何调用控制台?除了print以外的其他构造或在不引用带引号的字符串时，您是否有问题?

I tried version Jython 2.2.1, it was ok, but the problem remains in version Jython 2.7b1:

解决方案

Perhaps this is specific to the OS or machine environment, as it behaves for me on windows in 2.7.0 and have seen it behave in previous versions.

What is the underlying OS and how are you invoking the console? Do you have the problem with constructs other than print or when not referencing a quoted string?
