将字节转换为str python2.7

Question

I have a dictionary

k ={'Creator': '\xfe\xff\x00M\x00i\x00c\x00r\x00o\x00s\x00o\x00f\x00t\x00\xae\x00 \x00O\x00f\x00f\x00i\x00c\x00e\x00 \x00W\x00o\x00r\x00d\x00 \x002\x000\x000\x007'}

which is containing metadata of a pdf. In the pdf properties the Creator is Microsoft Office Word 2007. I am unable to convert k['Creator'] to 'Microsoft Office Word 2007' as in this case.

Answer 1

The data is encoded to UTF-16. Decode it:

print k['Creator'].decode('utf16')

This produces a unicode value; your console may or may not be able to handle the non-ASCII ® codepoint that includes.

Demo:

>>> k ={'Creator': '\xfe\xff\x00M\x00i\x00c\x00r\x00o\x00s\x00o\x00f\x00t\x00\xae\x00 \x00O\x00f\x00f\x00i\x00c\x00e\x00 \x00W\x00o\x00r\x00d\x00 \x002\x000\x000\x007'}
>>> print k['Creator'].decode('utf16')
Microsoft® Office Word 2007

Answer 2

This gives the required string.

Code :

>>> print(k['Creator'].decode('utf16','ignore')).encode('utf-8') 
Microsoft® Office Word 2007 
>>> type((k['Creator'].decode('utf16','ignore')).encode('utf-8')) 
<type 'str'>
