寻找一种更 Pythonic 的方式来将一个充满字典的列表合并成一个？

Question

I have a list with a bunch of dictionaries that I am trying to combine into one

Looks like this...

[{'name':'name', 'value':'john'}, {'name':'sex', 'value':'male'}, {'name':'color', 'value':'blue'}, {'name':'car', 'value':'toyota'}, {'name':'job', 'value':'cashier'}]

I'm trying to combine them all into one dictionary so that the name value is the key and the value is the value. Right now I'm doing something like this and it works fine but I know there is an easier way

keys = []
vals = []

for item in a:
    if item['name']:
        keys.append(item['name'])

    if item['value']:
        vals.append(item['value'])

md = dict(zip(keys,vals))

Any guidance would be appreciated... thank you

Answer 1

您可以使用字典理解。

new = {i['name']:i['value'] for i in a}

Answer 2

假设你的字典列表被称为 dict_list 你可以使用字典理解如下：

new_dict = { dict['name'] : dict['value'] for dict in dict_list}

Answer 3

您可以直接将dict.values()用于您的特定情况，因为键和值按顺序提供：

dict(d.values() for d in a)

Answer 4

You can do something like this also.

input_dict_list = [{'name':'name', 'value':'john'}, {'name':'sex', 'value':'male'}, {'name':'color', 'value':'blue'}, {'name':'car', 'value':'toyota'}, {'name':'job', 'value':'cashier'}]

out_put_dict = {}
for input_dict in input_dict_list:
    out_put_dict[input_dict['name']] = input_dict['value']

print(out_put_dict)
