从python中的字典转换为列表的问题[重复]

Question

我已经将我的字典转换为列表，但在获取特定格式时卡住了。我的输出字典是，

foldersinlist = [['Training'], ['Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']]

我想要的，

['Training', 'Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']

我目前拥有的代码如下，

foldersinlist = list(folders.values())
print(foldersinlist)

Answer 1

这是嵌套列表而不是字典：

foldersinlist = [['Training'], ['Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']]

这是平面列表：

['Training', 'Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']

只是做：

ll = sum(foldersinlist , [])

Answer 2

试试：

print([x for i in foldersinlist for x in i])

输出：

['Training', 'Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']
