统一写入文件时，$ C $岑codeError [英] UnicodeEncodeError when writing to a file

问题描述

我尝试一些字符串写入一个文件（字符串已被HTML解析器BeautifulSoup给我）。

I am trying to write some strings to a file (the strings have been given to me by the HTML parser BeautifulSoup).

我可以使用打印，以显示他们，但是当我使用file.write（）我收到以下错误：

I can use "print" to display them, but when I use file.write() I get the following error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in position 6: ordinal not in range(128)

有没有人见过这个？

Has anyone seen this before?

推荐答案

在传递一个包含非英文字符（统一code字符超过128）的东西，期望一个一个统一code字符串出现此错误ASCII字节字符串。对于一个Python字节字符串的默认编码为ASCII，这正是处理128（英文）字符。这就是为什么尝试转换的Uni code字符超出128产生错误。

This error occurs when you pass a Unicode string containing non-English characters (Unicode characters beyond 128) to something that expects an ASCII bytestring. The default encoding for a Python bytestring is ASCII, "which handles exactly 128 (English) characters". This is why trying to convert Unicode characters beyond 128 produces the error.

单向code（）

unicode(string[, encoding, errors])

构造函数签名UNI code（字符串[，编码，错误]）。它的所有参数应该是8位的字符串。

constructor has the signature unicode(string[, encoding, errors]). All of its arguments should be 8-bit strings.

第一个参数是使用指定的编码转换成统一code; 如果你离开了编码参数，ASCII编码用于转换，所以字符大于127将被视为错误

The first argument is converted to Unicode using the specified encoding; if you leave off the encoding argument, the ASCII encoding is used for the conversion, so characters greater than 127 will be treated as errors

例如：

s = u'La Pe\xf1a' 
print s.encode('latin-1')

或

write(s.encode('latin-1'))

将连接code使用Latin-1

will encode using latin-1
