为什么下面的项目失败了?为什么它成功与“拉丁-1”编解码器?

o = "a test of \xe9 char" #I want this to remain a string as this is what I am receiving
v = o.decode("utf-8")

结果是:

 Traceback (most recent call last):  
 File "<stdin>", line 1, in <module>  
 File "C:\Python27\lib\encodings\utf_8.py",
 line 16, in decode
     return codecs.utf_8_decode(input, errors, True) UnicodeDecodeError:
 'utf8' codec can't decode byte 0xe9 in position 10: invalid continuation byte

当前回答

当我试图通过pandas.read_csv打开CSV文件时,我遇到了同样的错误 方法。

解决方案是将编码改为latin-1:

pd.read_csv('ml-100k/u.item', sep='|', names=m_cols , encoding='latin-1')

其他回答

当你在pandas中输入一个特定的文件或数据时,这种类型的错误就会出现:-

data=pd.read_csv('/kaggle/input/fertilizers-by-product-fao/FertilizersProduct.csv)

错误显示如下:- UnicodeDecodeError: 'utf-8' codec不能解码字节0xf4在位置1:无效的延续字节

因此,为了避免这种类型的错误,可以通过添加参数来删除

data=pd.read_csv('/kaggle/input/fertilizers-by-product-fao/FertilizersProduct.csv', encoding='ISO-8859-1')

解决方案改为“UTF-8 sin BOM”

无效UTF-8。该字符是ISO-Latin1中的e-锐角字符,这就是它成功使用该代码集的原因。

如果你不知道你接收字符串的代码集,你就有麻烦了。最好是为您的协议/应用程序选择一个代码集(最好是UTF-8),然后您就拒绝那些没有解码的代码集。

如果你不能这样做,你就需要启发式。

TLDR:我建议在切换编码器以消除错误之前深入调查问题的根源。

我得到这个错误,因为我正在处理大量的zip文件,其中有额外的zip文件。

我的工作流程如下:

读取zip 读取子zip 读取子zip中的文本

At some point I was hitting the encoding error above. Upon closer inspection, it turned out that some child zips erroneously contained further zips. Reading these zips as text lead to some funky character representation that I could silence with encoding="latin-1", but which in turn caused issues further down the line. Since I was working with international data it was not completely foolish to assume it was an encoding problem (I had problems with 0xc2: Â), but in the end it was not the actual issue.

因为UTF-8是多字节的,并且没有对应于\xe9加上后面空格的组合的字符。

为什么它在utf-8和latin-1中都能成功?

下面是同一句话在utf-8中的用法:

>>> o.decode('latin-1').encode("utf-8")
'a test of \xc3\xa9 char'
