将unicode字符串更改为列表？

Question

我得到的数据类型<type 'unicode'>

u'{0.128,0.128,0.133,0.137,0.141,0.146,0.15,0.155,0.159,0.164,0.169,0.174,0.179,0.185,0.19,0.196,0.202,0.208,0.214,0.22}' 

我想转换此列出像

[0.128,0.128,0.133,0.137,0.141,0.146,0.15,0.155,0.159,0.164,0.169,0.174,0.179,0.185,0.19,0.196,0.202,0.208,0.214,0.22] 

我怎样才能做到这一点与Python？

谢谢

Answer 1

就像这样：

>>> a = u'{0.128,0.128,0.133,0.137,0.141,0.146,0.15,0.155,0.159,0.164,0.169,0.174,0.179,0.185,0.19,0.196,0.202,0.208,0.214,0.22}' 
>>> [float(i) for i in a.strip('{}').split(',')] 
[0.128, 0.128, 0.133, 0.137, 0.141, 0.146, 0.15, 0.155, 0.159, 0.164, 0.169, 0.174, 0.179, 0.185, 0.19, 0.196, 0.202, 0.208, 0.214, 0.22] 

Unicode是非常相似的str，你可以使用.split()，以及strip()。此外，铸造到float的工作方式为str。

所以，首先通过使用.strip('{}')剥离您的不必要的大括号（{和}）的串，然后分裂，通过使用.split(',')逗号（,）生成的字符串。之后，您可以使用列表理解，将每个项目转换为float，如上例所示。

出我的头和未经考验的：

data = u'your string with braces removed' 
aslist = [float(x) for x in data.split(',')]
