合并字典并在列表中有一个大字典

Question

payload =  [
                {
                    "Beds:": "3"
                },
                {
                    "Baths:": "2.0"
                },
                {
                    "Sqft:": "1,260"
                },

            ]

我怎么会有这样的清单：

payload = [{'Beds':"3","Baths":"2.0","Sqft":"1,260"}]

而不是多个词典;我想在列表中找到一本字典。

Answer 1

试试这个：

payload_new = [{i: j[i] for j in payload for i in j}]

Answer 2

这应该有所帮助。使用replace方法删除＆＃34;：＆＃34;

payload =  [
                {
                    "Beds:": "3"
                },
                {
                    "Baths:": "2.0"
                },
                {
                    "Sqft:": "1,260"
                },

            ]


newDict = [{k.replace(":", ""): v for j in payload for k,v in j.items()}]
print newDict

<强>输出：

[{'Beds': '3', 'Sqft': '1,260', 'Baths': '2.0'}]

Answer 3

Python 3内置字典展开，试试这个

payload = {**payload_ for payload_ in payload}

Answer 4

要在大字典中合并字典，您可以这样写：

payload={"Beds": 3 ,
         "Baths": 2.0,
         "Sqft": 1260
        }

输出：

>>>payload["Baths"]
2.0

<强>视图：

• 使用[]使其成为数组/列表而非字典。
• 在密钥上使用""（例如：＆＃34; 3＆＃34;）使它们成为字符串而不是整数。
