Python从元组列表中提取元素

Question

我正在尝试从元组列表中提取元素。 我得到了答案，但想知道有没有更好的方法？ 代码：

pred_result_tuple  = [('n02123045', 'tabby', 0.5681726)]
pred_result_list = [x[n] for x in pred_result_tuple for n in [0,1,2]]

print(pred_result_list)
['n02123045', 'tabby', 0.5681726]

尝试但失败：

print([x[n] for x,n in zip(pred_result_tuple,[0,1,2])])
['n02123045']

Answer 1

import itertools
result = list(itertools.chain(*pred_result_tuple))

>>> print(result)
>>> ['n02123045', 'tabby', 0.5681726]

但是，如果您在list中只有一个tuple ，您可以这样做：

result = list(*pred_result_tuple)

>>> print(result)
>>> ['n02123045', 'tabby', 0.5681726]

Answer 2

利用

Listoftuples=[(#elements)]
l=[]
for e in Listoftuples[0]:
    l=l+[e]
print(l)

结果

[#elements]
