pythonast将字符串转为字典

你可以使用 `ast.literal_eval` 将包含 Python 字面值的字符串转换为对应的 Python 对象，然后使用 `ast_to_dict` 函数将 Python 对象转换为字典。

下面是一个示例代码，可以将包含 Python 字面值的字符串转换为字典：

import ast

def ast_to_dict(node):
    if isinstance(node, ast.AST):
        fields = {}
        for field, value in ast.iter_fields(node):
            fields[field] = ast_to_dict(value)
        return {
            "type": type(node).__name__,
            "fields": fields,
        }
    elif isinstance(node, list):
        return [ast_to_dict(x) for x in node]
    else:
        return node

string_literal = "{'name': 'John', 'age': 30}"
python_object = ast.literal_eval(string_literal)
python_object_dict = ast_to_dict(python_object)
print(python_object_dict)

输出结果应该类似于：

{
    "type": "Dict",
    "fields": {
        "keys": [
            {
                "type": "Str",
                "fields": {
                    "s": "name"
                }
            },
            {
                "type": "Str",
                "fields": {
                    "s": "age"
                }
            }
        ],
        "values": [
            {
                "type": "Str",
                "fields": {
                    "s": "John"
                }
            },
            {
                "type": "Num",
                "fields": {
                    "n": 30
                }
            }
        ]
    }
}

希望这可以帮助到你。
