如何在python中将参数传递给JMES路径表达式

import jmespath

# 定义JSON数据
data = {
    "employees": [
        {
            "name": "John",
            "age": 30,
            "department": "IT"
        },
        {
            "name": "Alice",
            "age": 35,
            "department": "HR"
        },
        {
            "name": "Bob",
            "age": 25,
            "department": "Finance"
        }
    ]
}

# 定义JMES路径表达式
expression = "employees[?age > `{{age}}`].name"

# 定义参数
params = {
    "age": 30
}

# 创建JMES路径对象
jmespath_expr = jmespath.compile(expression)

# 使用参数传递给JMES路径表达式
result = jmespath_expr.search(data, params)

print(result)
