如何在Python中将字符串列表转换为字典列表

Question

我有这样的物品清单：

["{'Collaboration':5,'Communication':5,'Creativity':4,'Critical Thinking':4}", "{'Collaboration':5,'Communication':5,'Creativity':5,'Critical Thinking':4}"]

每个项目都是一个字典字符串。如何将字符串列表转换为字典列表。我需要这样的最终结果：

[{'Collaboration':5,'Communication':5,'Creativity':4,'Critical Thinking':4}, {'Collaboration':5,'Communication':5,'Creativity':5,'Critical Thinking':4}]

Answer 1

导入并使用literal_eval。这就是我的工作。

import ast
lst = ["{'Collaboration':5,'Communication':5,'Creativity':4,'Critical Thinking':4}", "{'Collaboration':5,'Communication':5,'Creativity':5,'Critical Thinking':4}"]
res = [ast.literal_eval(x) for x in lst]
print(res)

Answer 2

为此，您应该使用json.loads。您的字符串使用单引号封装字符串。对于JSON，您必须用双引号替换它们。

import json
l = ["{'Collaboration':5,'Communication':5,'Creativity':4,'Critical Thinking':4}", "{'Collaboration':5,'Communication':5,'Creativity':5,'Critical Thinking':4}"]
result = [json.loads(x.replace("'", '"')) for x in l]
