将unicode转换为unicode转义语法(Convert unicode to unicode escape syntax)

 unicode对象u"ÿ"在Python中给出。 如何将其转换为相应的unicode转义语法"\\u00FF" ？ 无法让unicode-escape在这里工作。 
 
 编辑：在我的情况下，给出一个字符串对象，内容为r"\u00FF" 。 另一方面，我有一个unicode对象（从上面），我需要进行字符串比较以检查它们是否相等。 我需要unicode转义语法作为来自上面的unicode字符的字符串对象来做到这一点。 

The unicode object u"ÿ" is given in Python. How can I convert it to the corresponding unicode escape syntax "\\u00FF"? Couldn't get unicode-escape to work here.
 
Edit: In my case a string object is given with the content r"\u00FF". On the other side I have a unicode object (from above) and I need to make a string comparison to check if they are equal. I need the unicode escape syntax as a string object from the unicode character from above to do that.
