Question

我有一个混合列表，如下所示：

[('1CFV',), 'NONRBP', [0.00325071141379, 0.278046326931, 0.291350892759]]

它是使用此命令创建的：

In [12]: l1 =  [0.00325071141379, 0.278046326931, 0.291350892759]

In [13]: t1 = ('1CFV',)                                                          

In [14]: s1 = "NONRBP"

In [15]: mixl = [t1,s1,l1]

In [16]: mixl

有没有办法将其转换为：

   ['1CFV', 'NONRBP', 0.00325071141379, 0.278046326931, 0.291350892759]

我尝试了这个，但它甚至弄平了字符串'NONRBP'，这不是我想要的：

 [item for sublist in mixl for item in sublist]

Answer 1

>>> final = []
>>> a = [('1CFV',), 'NONRBP', [0.00325071141379, 0.278046326931, 0.291350892759]]
>>> for i in a:
...   if hasattr(i, '__iter__'):
...     for j in i:
...       final.append(j)
...   else:
...     final.append(i)
... 
>>> print final
['1CFV', 'NONRBP', 0.00325071141379, 0.27804632693100001, 0.291350892759]

Answer 2

[item for item in list if type(item) is not list] + 
[item for sublist in mixl if type(item) is list for item in sublist]

解决列表包含列表和其他可迭代项（字符串）的特定情况

扁平化混合类型的列表
