python将两个元组列表组合成一个大元组列表？(python combining two lists of tuples into one big list of tuples? [duplicate])

这个问题在这里已有答案：

如何在Python中连接两个列表？ 28个答案 Python成语链（flatten）无限可迭代的有限迭代？ [重复] 2个答案

我四处搜索，似乎没有人问过这个问题（或者至少我找不到它）。

我有两个元组列表，我想将它们加入到一个元组列表中。

first = [('a', 1), ('b',2)] second = [('c',3), ('d',4)]

我试过追加，加入，拉链，但没有一个是正确的。 我想得到这个：

wanted = [('a', 1), ('b',2), ('c',3), ('d',4)]

有一个简单的方法吗？

编辑：我觉得真的很蠢......当然这是我忘记尝试的一件事:(

How do I concatenate two lists in Python? 28 answers Python idiom to chain (flatten) an infinite iterable of finite iterables? [duplicate] 2 answers

I've searched around and it seems like nobody has asked this question (or at least I can't find it).

I have two lists of tuples and I want to join them to one list of tuples.

first = [('a', 1), ('b',2)] second = [('c',3), ('d',4)]

I have tried appending, joining, zipping, but none of those are quite right. I want to get this:

wanted = [('a', 1), ('b',2), ('c',3), ('d',4)]

Is there a simple way to do this?

EDIT: I feel really stupid... of course its the one thing I forgot to try :(

最满意答案

你可以用+

>>> first = [('a', 1), ('b',2)] >>> second = [('c',3), ('d',4)] >>> first + second [('a', 1), ('b', 2), ('c', 3), ('d', 4)]

You can use +

>>> first = [('a', 1), ('b',2)] >>> second = [('c',3), ('d',4)] >>> first + second [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
