下面是使用列表理解的一种方法。注意**语法需要python3.6。你知道吗

lst = [{'A': 1}, {'B': 2}, {'C': 3}, {'D': 4}] 

res = [{**lst[0], **i} for i in lst[1:]]

[{'A': 1, 'B': 2}, {'A': 1, 'C': 3}, {'A': 1, 'D': 4}]

在Python 2.7中，可以定义一个函数来执行合并：

def merge_dicts(x, y):
    z = x.copy()
    z.update(y)
    return z

res = [merge_dicts(lst[0], i) for i in lst[1:]]

抱歉，我只看了你问题的前三行，这似乎足够了。我建议，如果这解决了你的问题，你相应地更新你的问题。你知道吗
