转换数组列表

Question

我是python的新手.如何转换这样的数组:

x=[[0.3], [0.07], [0.06]]

成:

x=[0.3,0.07, 0.06]

？提前致谢.

Answer 1

以下列表理解可能有用.

>>> x=[[0.3], [0.07], [0.06]]
>>> y = [a for [a] in x]
>>> y
[0.3, 0.07, 0.06]

考虑到内在值也是类型list.

cdhowie给出的类似但更易读的代码如下.

>>> x=[[0.3], [0.07], [0.06]]
>>> y = [a[0] for a in x]
>>> y
[0.3, 0.07, 0.06]
