如何只整理内部列表？

Question

清单：

results = [['04-25', [1, 2, 3, 4]], ['04-26', [5, 6, 7, 8]], ['04-27', [9, 20, 11, 21]]

尝试获取此输出：

[['04-25', 1, 2, 3, 4], ['04-26', 5, 6, 7, 8], ['04-27', 9, 20, 11, 21]]

我已经试过了：

data = [a for b in [_ for _ in results[i]] for a in b]

它将列表中的每个字符分成一个不同的元素，如下所示：

['0', '4', '-', '2', '5', 1, 2, 3, 4]

如何访问和展平内部列表？

Answer 1

使用*开箱：

results = [['04-25', [1, 2, 3, 4]], ['04-26', [5, 6, 7, 8]], ['04-27', [9, 20, 11, 21]]]

data = [[a, *b] for a,b in results]

print(data)

输出：

[['04-25', 1, 2, 3, 4], ['04-26', 5, 6, 7, 8], ['04-27', 9, 20, 11, 21]]

Answer 2

您可以添加第一个值和内部list：

[[i] + j for i, j in results]

输出：

[['04-25', 1, 2, 3, 4], ['04-26', 5, 6, 7, 8], ['04-27', 9, 20, 11, 21]]
