问题
I'm trying to write out to a flat file some Chinese, or Russian or various non-English character-sets for testing purposes. I'm getting stuck on how to output a Unicode hex-decimal or decimal value to its corresponding character.
For example in Python, if you had a hard coded set of characters like абвгдежзийкл you would assign value = u"абвгдежзийкл" and no problem.
If however you had a single decimal or hex decimal like 1081 / 0439 stored in a variable and you wanted to print that out with it's corresponding actual character (and not just output 0x439) how would this be done? The Unicode decimal/hex value above refers to й.
回答1:
Python 2: Use unichr():
>>> print(unichr(1081))
й
Python 3: Use chr():
>>> print(chr(1081))
й

So the answer to the question is:
- convert the hexadecimal value to decimal with
int(hex_value, 16) - then get the corresponding strin with
chr().
To sum up:
>>> print(chr(int('0x897F', 16)))

If you run into the error:
ValueError: unichr() arg not in range(0x10000) (narrow Python build)
While trying to convert your hex value using unichr, you can get around that error by doing something like:
>>> n = int('0001f600', 16)
>>> s = '\\U{:0>8X}'.format(n)
>>> s
'\\U0001F600'
>>> binary = s.decode('unicode-escape')
>>> print(binary)
