我正在尝试使用此功能:
import unicodedata
def remove_accents(input_str):
nkfd_form = unicodedata.normalize('NFKD', unicode(input_str))
return u"".join([c for c in nkfd_form if not unicodedata.combining(c)])
在下面的代码中(它解压缩并读取具有非 ASCII 字符串的文件)。但是我收到了这个错误,(来自这个库文件C:\Python27\Lib\encodings\utf_8.py
):
Message File Name Line Position
Traceback
<module> C:\Users\CG\Desktop\Google Drive\Sci&Tech\projects\naivebayes\USSSALoader.py 64

remove_accents C:\Users\CG\Desktop\Google Drive\Sci&Tech\projects\naivebayes\USSSALoader.py 17
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 3: ordinal not in range(128)
为什么我会收到此错误?如何避免它并发挥remove_accents
作用?
谢谢你的帮助!
这是整个代码:
