提问by kols

I capture the string from a html source file using regex:

我使用正则表达式从 html 源文件中捕获字符串:

f = open(rrfile, 'r')
p = re.compile(r'"name":"([^"]+)","head":"([^"]+)"')
match = re.findall(p, f.read())

And I've tried:

我试过:

>>> u'\u4f60\u4f60'.replace('\u', '\u')  
u'\u4f60\u4f60'  
>>> u'\u4f60\u4f60'.replace(u'\u', '\u')  
u'\u4f60\u4f60'  
>>> u'\u4f60\u4f60'.replace('\u', u'\u')  
File "<stdin>", line 1  
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 0-1: end of string in escape sequence  

Could that be done by str.replace()? Or need something more complex?

可以通过 str.replace() 来完成吗?或者需要更复杂的东西?
