Question

给定一个unicode对象：

u'[obj1,obj2,ob3]'

如何将其转换为正常的对象列表？

Answer 1

import ast
s = u'[obj1,obj2,ob3]'
n = ast.literal_eval(s)
n
[obj1, obj2, ob3]

Answer 2

你是说这个意思吗？将unicode字符串转换为字符串列表。顺便说一句，在处理unicode时你需要知道编码。在这里我使用了utf-8

>>> s = u'[obj1,obj2,ob3]'
>>> n = [e.encode('utf-8') for e in s.strip('[]').split(',')]
>>> n
['obj1', 'obj2', 'ob3']

Answer 3

您发布的是unicode字符串。要编码它，例如因为UTF-8使用yourutf8str = yourunicodestr.encode('utf-8')

Answer 4

当unicode数据未显示unicode时...

使用openpyxl从excel表导出数据时，我的unicode是不可见的。使用print repr(s)查看

>>>print(data)
>>>print(type(data))
["Independent", "Primary/Secondary Combined", "Coed", "Anglican", "Boarding"]
<type 'unicode>
>>>print repr(data)
u'["Independent", "Primary/Secondary Combined", "Coed", "Anglican", "Boarding"]'

修复：

>>>import ast    
>>>data = ast.literal_eval(entry)
>>>print(data)
>>>print(type(data))
["Independent", "Primary/Secondary Combined", "Coed", "Anglican", "Boarding"]
<type 'list'>
