问题描述
我在读取文本文件时不断收到此错误.是否可以处理/忽略它并继续?
I keep getting this error while reading a text file. Is it possible to handle/ignore it and proceed?
UnicodeEncodeError: ‘charmap’ 编解码器无法解码字节 0x81 的位置7827:字符映射到未定义.
推荐答案
在 Python 3 中,传递适当的 errors=
值(例如 errors=ignore
或 >errors=replace
) 创建您的文件对象(假设它是 io.TextIOWrapper
的子类——如果不是,请考虑将其包装成一个!);此外,请考虑传递比 charmap
更有可能的编码(当您不确定时,utf-8
始终是一个不错的起点).
In Python 3, pass an appropriate errors=
value (such as errors=ignore
or errors=replace
) on creating your file object (presuming it to be a subclass of io.TextIOWrapper
-- and if it isn't, consider wrapping it in one!); also, consider passing a more likely encoding than charmap
(when you aren't sure, utf-8
is always a good place to start).
例如:
f = open('misc-notes.txt', encoding='utf-8', errors='ignore')
在 Python 2 中,read()
操作只返回字节;然后,诀窍是将它们解码以将它们转换为字符串(如果您这样做,实际上,需要字符而不是字节).如果您对它们的真实编码没有更好的猜测:
In Python 2, the read()
operation simply returns bytes; the trick, then, is decoding them to get them into a string (if you do, in fact, want characters as opposed to bytes). If you don't have a better guess for their real encoding:
your_string.decode('utf-8', 'replace')
...替换未处理的字符,或
...to replace unhandled characters, or
your_string.decode('utf-8', 'ignore')
简单地忽略它们.
也就是说,最好找到并使用他们的真实编码(而不是猜测utf-8
).
That said, finding and using their real encoding (rather than guessing utf-8
) would be preferred.
