Windows命令行下Python交互的问题

>>> dict2={'name':'earth','port':80}
>>> for key, value in dict2.items():
... print 'key=%s,value=%s' % (key,value)
  File "<stdin>", line 2
  print 'key=%s,value=%s'% (key,value)


如上：怎么会出现错误呢？？？

Python code

>>> dict2.items()
[('name', 'earth'), ('port', 80)]
>>> for i in dict2.items():
    print i

    
('name', 'earth')
('port', 80)
>>> for key in dict2:
    print key,dict2[key]

    
name earth
port 80
>>>
