如何输出utf-8字符串列表，就像在python中一样? [英] How to output a utf-8 string list as it is in python?

问题描述

嗯，字符编码和解码有时让我非常沮丧.

Well, character encoding and decoding sometimes frustrates me a lot.

所以我们知道u'\u4f60\u597d'是你好的utf-8编码

>>> print hellolist
[u'\u4f60\u597d']
>>> print hellolist[0]
你好

现在我真正想从输出或写入文件中得到的是[u'你好']，但是一直都是[u'\u4f60\u597d']，那么你怎么做呢?

Now what I really want to get from the output or write to a file is [u'你好'], but it's [u'\u4f60\u597d'] all the time, so how do you do it?

推荐答案

打印(或写入文件)列表时，列表内部调用列表的str()方法，但是列表内部对其列表调用repr()元素. repr()返回您所看到的难看的unicode表示形式.

When you print (or write to a file) a list it internally calls the str() method of the list , but list internally calls repr() on its elements. repr() returns the ugly unicode representation that you are seeing .

repr的示例-

>>> h = u'\u4f60\u597d'
>>> print h
\u4f60\u597d
>>> print repr(h)
u'\u4f60\u597d'

您需要手动获取列表中的元素并进行打印，以使其正确打印.

You would need to manually take the elements of the list and print them for them to print correctly.

示例-

>>> h1 = [h,u'\u4f77\u587f']
>>> print u'[' + u','.join([u"'" + unicode(i) + u"'" for i in h1]) + u']'

对于包含可能具有unicode字符的子列表的列表，您将需要一个递归函数，例如-

For lists containing sublists that may have unicode characters, you would need a recursive function , example -

>>> h1 = [h,(u'\u4f77\u587f',)]
>>> def listprinter(l):
...     if isinstance(l, list):
...             return u'[' + u','.join([listprinter(i) for i in l]) + u']'
...     elif isinstance(l, tuple):
...             return u'(' + u','.join([listprinter(i) for i in l]) + u')'
...     elif isinstance(l, (str, unicode)):
...             return u"'" + unicode(l) + u"'"
... 
>>> 
>>> 
>>> print listprinter(h1)

要将它们保存到文件中，请使用相同的列表理解或递归函数.示例-

To save them to file, use the same list comprehension or recursive function. Example -

with open('<filename>','w') as f:
    f.write(listprinter(l))
