如何在python中从西班牙语进行编码和解码

Question

I have the following code written in python 2.7

# -*- coding: utf-8 -*-    
import sys

_string = "años luz detrás"
print _string.encode("utf-8")

this throws the following error:

print _string.encode("utf-8")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128)

Any help appreciated, thanks in advance

Answer 1

Add u before the "

>>> _string = u"años luz detrás"
>>> print _string.encode("utf-8")
años luz detrás

This would do.

Answer 2

In Python 2 a string literal "" creates a bytestring. Then you call .encode("utf-8") on a bytestring, Python tries first to decode it into Unicode string using a default character encoding ( ascii ) before executing .encode("utf-8") .

u"" creates Unicode string. It will fix the UnicodeDecodeError as @Bleeding Fingers suggested .

# -*- coding: utf-8 -*-    
print u"años luz detrás"

It might lead to UnicodeEncodeError if stdout is redirected. Set PYTHONIOENCODING environment variable in this case.
