在python中从十六进制字符转换为Unicode字符

Question

The hex string '\\xd3' can also be represented as: Ó .

The easiest way I've found to get the character representation of the hex string to the console is:

print unichr(ord('\xd3'))

Or in English, convert the hex string to a number, then convert that number to a unicode code point, then finally output that to the screen. This seems like an extra step. Is there an easier way?

Answer 1

print u'\xd3'

Is all you have to do. You just need to somehow tell Python it's a unicode literal; the leading u does that. It will even work for multiple characters.

If you aren't talking about a literal, but a variable:

codepoints = '\xd3\xd3'
print codepoints.decode("latin-1")

Edit: Specifying a specific encoding when print ing will not work if it's incompatible with your terminal encoding, so just let print do encode(sys.stdout.encoding) automatically. Thanks @ThomasK.

Answer 2

if data is something like this "\\xe0\\xa4\\xb9\\xe0\\xa5\\x88\\xe0\\xa4\\xb2\\xe0\\xa5\\x8b \\xe0\\xa4\\x95\\xe0\\xa4\\xb2"

sys.stdout.buffer.write(data) 

would print
