如何在python中更正一个Unicode字符串，如“ \\ u8bf8 \\ u845b \\ u4eae”？

Question

I don't know how they printed strings like "\诸\葛\亮" to the log files. But now i need to get the correct string from it, it is "诸葛亮" in chinese. I have tried many ways, but failed.

In [56]: print u"\u8bf8\u845b\u4eae"
诸葛亮

In [57]: print "\u8bf8\u845b\u4eae"
\u8bf8\u845b\u4eae

In [58]: "\u8bf8\u845b\u4eae".decode('utf-8')
Out[58]: u'\\u8bf8\\u845b\\u4eae'
In [64]: eval("\u8bf8\u845b\u4eae")
  File "<string>", line 1
    \u8bf8\u845b\u4eae
                 ^
SyntaxError: unexpected character after line continuation character

You have to use: unicode-escape

print '\\u8bf8\\u845b\\u4eae'.encode('ascii').decode('unicode-escape')
