help() 与 unicode author 字符串

发布于 2024-11-15 12:51:29 字数 1066 浏览 3 评论 0原文

在 Python 2.6 脚本的开头，我想按照拼写写下我的名字，即“Joël”（e 上带有 trema）。所以我写了 __author__ = u'Joël'，并且我可以通过简单的 print __author__ 来检索它。

内置 help() 函数出现问题，因为我收到一条错误消息：

UnicodeEncodeError: 'ascii' codec can't encode character u'\xeb' in position 2: ordinal not in range(128)

我无法升级到 Python 3.x，并且我发现这个函数非常有帮助（并且它肯定对那些谁会得到我的脚本）。我也没有忘记用 UTF-8 对文件进行编码，并通过添加以下内容在脚本中指定它：

# -*- coding: utf-8 -*-

知道它来自哪里吗？

预先感谢您的回答。

编辑再次查看“Dive Into Python”一书，我发现如何在我的机器上进行正确的渲染，请参阅 http://www.diveintopython.org/xml_processing/unicode.html。

我的想法是，我的 Python 默认编码是 ASCII，这确实阻止了 help() 做出正确的输出。我所做的是在 {pythondir}\Lib\site-packages 中添加一个名为 sitecustomize.py 的脚本，设置默认编码：

import sys
sys.setdefaultencoding('iso-8859-1')

现在，使用输入字符串像u'Joël'一样编写，我通过调用help()得到了正确的输出。

问题是，我很确定这会在其他计算机上崩溃。知道我该如何处理这个问题吗？

原文

In the beginning of my scripts in Python 2.6, I would like to write my name as it is spelled, i.e. "Joël" (with trema on e). So I write __author__ = u'Joël', and I can retrieve it by a simple print __author__.

Problem appears with the built-in help() function, as I get an error message:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xeb' in position 2: ordinal not in range(128)

I cannot upgrade to Python 3.x, and I find this function very helpful (and it will surely be for those who will get my scripts). I also did not forget to encode the files in UTF-8, and to specify it in the scripts by adding this:

# -*- coding: utf-8 -*-

Any idea on where this comes from?

Thanks in advance for your answers.

EDIT
Looking to the "Dive Into Python" book again, I found out how to have a correct render on my machine, see http://www.diveintopython.org/xml_processing/unicode.html.

The idea is that, my default encoding for Python was ASCII, and this did prevent help() to make a correct output. What I did is to add a script named like sitecustomize.py in {pythondir}\Lib\site-packages, setting the default encoding:

import sys
sys.setdefaultencoding('iso-8859-1')

And now, with an input string written like u'Joël', I get a correct output through call of help().

Problem is, I'm quite sure that this will break on other's computers. Any idea how I could handle this?

Pydoc 明确希望将作者姓名转换为 ascii：

  File "/usr/local/Cellar/python/2.7.1/lib/python2.7/pydoc.py", line 1111, in docmodule
    result = result + self.section('AUTHOR', str(object.__author__))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xeb' in position 2: ordinal not in range(128)

您不太可能解决这个问题。

Pydoc explicitly wants to convert the author name to ascii:

  File "/usr/local/Cellar/python/2.7.1/lib/python2.7/pydoc.py", line 1111, in docmodule
    result = result + self.section('AUTHOR', str(object.__author__))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xeb' in position 2: ordinal not in range(128)

It’s unlikely that you can work around this.
