我有一个以UTF-8编码的.csv文件,其中包含拉丁文和西里尔符号。
;F1;F2;abcdefg3;F200
;ABSOLUTE;NOMINAL;NOMINAL;NOMINAL
o1;1;USA;Новосибирск;1223
我正在尝试在IronPython 2.7.1中执行以下脚本:
import codecs
f = codecs.open(r"file.csv", "rb", "utf-8")
f.next()
在执行f.next()期间,会发生异常:
Traceback (most recent call last):
File "c:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\Python Tools for Visual Studio\1.1\visualstudio_py_repl.py", line 492, in run_file_as_main
code.Execute(self.exec_mod)
File "<string>", line 4, in <module>
File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 684, in next
return self.reader.next()
File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 615, in next
line = self.readline()
File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 530, in readline
data = self.read(readsize, firstline=True)
File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 477, in read
newchars, decodedbytes = self.decode(data, self.errors)
UnicodeEncodeError: ('unknown', '\x00', 0, 1, '')
在CPython 2.7的同时,脚本可以正常工作。同样在IronPython 2.7.1下面的脚本工作正常:
import codecs
f = codecs.open(r"file.csv", "rb", "utf-8")
f.readlines()
有人知道可能导致这种奇怪行为的原因吗?
答案 0 :(得分:2)
看起来它可能是next()
处理编解码器的错误。你能否open an issue请复制附件?
答案 1 :(得分:0)
可能是“rb”参数出现问题,请尝试使用“r”
f = codecs.open(r"file.csv", "r", "utf-8")
