这种方法对我很有效:

object = [{'a':1}, {'b':2}, {'c':1}, {'d':2}]
object = {k: v for dct in object for k, v in dct.items()}

打印对象:

object = {'a':1,'b':2,'c':1,'d':2}

由于轴

@dietbuddha回答从PEP 448字典解包略有改进，对我来说，这样更可读，而且也更快:

from functools import reduce
result_dict = reduce(lambda a, b: {**a, **b}, list_of_dicts)

但是请记住，这只适用于Python 3.5+版本。

这类似于@delnan，但提供了修改k/v(键/值)项的选项，我认为更易于阅读:

new_dict = {k:v for list_item in list_of_dicts for (k,v) in list_item.items()}

例如，替换k/v elems如下:

new_dict = {str(k).replace(" ","_"):v for list_item in list_of_dicts for (k,v) in list_item.items()}

将dict对象从列表中拉出后，从字典.items()生成器中解包k,v元组

对于平面字典，你可以这样做:

from functools import reduce
reduce(lambda a, b: dict(a, **b), list_of_dicts)

如果你不再需要单例字典:

>>> L = [{'a':1}, {'b':2}, {'c':1}, {'d':2}]
>>> dict(map(dict.popitem, L))
{'a': 1, 'b': 2, 'c': 1, 'd': 2}
