Question

我将数据设为类型<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}'

我想将此转换为列表，如

[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]

我怎么能用python做到这一点？

谢谢

Answer 1

就像那样：

>>> 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与str非常相似，您可以使用.split()以及strip()。此外，转换为float的方式适用于str。

因此，首先使用{去除不必要的花括号（}和.strip('{}')）的字符串，然后使用逗号（,）分割结果字符串.split(',')。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。

Answer 2

从我的头脑中未经测试：

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

将unicode字符串更改为列表？
