Question

这个问题已经有答案了:

Convert JSON string to dict using Python [duplicate] (4 个回答)

已关闭 5 年前。

我有这样的项目列表:

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

每一项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ast并使用literal_eval。这样就完成了工作。

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)
