Python：从数组元组列表到列表列表

Question

我不知道我是怎么弄乱代码属性的，但我最终得到了一个怪物：一个元素是元组的列表，其元素是数组......

如何转换元素以获得简单的列表列表？

Answer 1

它可能不是最快的，但这应该非常健壮：

lst = np.array(lst).tolist()

Answer 2

只需调用以下列表推导：

lst = [item.tolist() for item in lst]

运行如下：

>>> lst = [(array([ 0.00773887,  0.00531894,  0.00533349,  0.00779727,  0.01482933,
...     0.01247594,  0.01274703,  0.02111097,  0.01800994,  0.01398229,
...     0.0098171 ,  0.01218634,  0.00987849,  0.01082564,  0.00739867,
...     0.00930694,  0.01071009,  0.00871869,  0.00897236,         nan,
...     0.06841951,  0.03529371,         nan,  0.016373  ,  0.0160713 ,
...     0.0182685 ,         nan,  0.01816914,  0.01156275,  0.01283952,
...            nan,  0.00962016,  0.00861139,  0.00776996,  0.0324668 ,
...     0.00745239]))]
>>>
