将字典列表转换成字典 [英] Convert list of dictionaries into dict

问题描述

我有以下一元字典列表：

I have the following list of one-element dictionaries:

[{'\xe7': '\xe7\x95\xb6\xe6\x96\xb0\x.'}, {'...\xe6\x991\xe7\xa8\x': 'asdf'}]

我如何将其转换为字典？要获得：

How would I convert this into a dict? To get:

{
    '\xe7': '\xe7\x95\xb6\xe6\x96\xb0\x.',
    '...\xe6\x991\xe7\xa8\x': 'asdf'
}

推荐答案

您可以使用 dict理解 ：

{k:v for element in dictList for k,v in element.items()}

此语法仅适用于> = 2.7的Python版本。如果您使用的是Python< 2.7，您必须执行以下操作：

This syntax only works for Python versions >= 2.7 though. If you are using Python < 2.7, you'd have to do something like:

dict([(k,v) for element in dictList for k,v in element.items()])

如果您不熟悉这种理解，我所做的等同于：

If you're unfamiliar with such nesting inside a comprehension, what I've done is equivalent to:

newDict = {}
for element in dictList:
    for k,v in element.items():
        newDict[k] = v
