How do I unescape a unicode escaped string in python?

问题

I have a unicode escaped string:

> str = 'blah\\x2Ddude'

I want to convert this string into the unicode unescaped version 'blah-dude'

How do I do this?

回答1:

Encode it to bytes (using whatever codec, utf-8 probably works) then decode it using unicode-escape:

s = 'blah\\x2Ddude'

s.encode().decode('unicode-escape')
Out[133]: 'blah-dude'
