@c，你可以使用jsonpath库来执行表达式查询，它支持在JSON数据中进行灵活的查询操作。JSONPath是一种用于从JSON结构中提取数据的语言，类似于XPath用于XML文档。

你可以通过以下方式安装jsonpath库：

pip install jsonpath-ng

然后，你可以使用它来执行查询操作，例如：

import json
from jsonpath_ng import jsonpath, parse

# Example JSON data
data = {
    "store": {
        "book": [
            {"category": "reference", "author": "Nigel Rees", "title": "Sayings of the Century", "price": 8.95},
            {"category": "fiction", "author": "Evelyn Waugh", "title": "Sword of Honour", "price": 12.99},
            {"category": "fiction", "author": "Herman Melville", "title": "Moby Dick", "isbn": "0-553-21311-3", "price": 8.99},
            {"category": "fiction", "author": "J. R. R. Tolkien", "title": "The Lord of the Rings", "isbn": "0-395-19395-8", "price": 22.99}
        ],
        "bicycle": {"color": "red", "price": 19.95}
    },
    "expensive": 10
}

# Define your JSONPath expression
expression = parse("$.store.book[*].author")

# Execute the expression
matches = expression.find(data)

# Output the results
for match in matches:
    print(match.value)

这个例子中，我们使用JSONPath表达式$.store.book[*].author来查询所有书籍的作者。
