SyntaxError：不匹配的输入'print'期望INDENT

将Jython安装到Linux后，如何导入sys并打印详细信息？SyntaxError：不匹配的输入'print'期望INDENT

[email protected]:~$ 
[email protected]:~$ jython --version 
"my" variable $jythonHome masks earlier declaration in same scope at /usr/bin/jython line 15.

    print k, r[k] 
    ^

大概这个代码是针对Windows的，但仍应该执行。它们表示什么类型的缩进？我输入的内容与example完全相同。有没有空间或标签对我来说不明显？

我试图缩进了一下：

[email protected]:~$ 
[email protected]:~$ jython -i 
"my" variable $jythonHome masks earlier declaration in same scope at /usr/bin/jython line 15.

>>> import sys 
>>> r=sys.registry 
>>> for k in r: 
... print k, r[k] 
... ; 
    File "<stdin>", line 3 
    ; 
    ^
SyntaxError: mismatched input ';' expecting DEDENT 
>>> exit() 
[email protected]:~$

好的会做的。谢谢。 – Thufir

在输入'print k，r [k]'之前，您至少需要添加一个空格。 Python不使用关键字来标记循环/函数的结尾/ ...它使用缩进来知道这些结束的地方。 –

这意味着循环内需要打印'print' – ppasler

如果你们的人想分，我会接受你的回答当然。以下是我得到它的工作：

我知道，Python中的空白，但是，只要我可以告诉是继实例教程。不要防守，但他们可以提及按两次输入。无论如何，伟大的评论，谢谢，明白了。
