代码如下：

#encoding=utf-8
print '中国'

#根据字典内容，替换被标记的字符串

import string

new_style=string.Template('this is $thing')

print new_style.substitute({'thing':5})
print new_style.substitute({'thing':'test some'})


old_style='this is %(thing)s'
print old_style%{'thing':5}

打印结果如下：

中国
this is 5
this is test some
this is 5
