Python -检查签名注解是否属于特定类

import inspect

class MyClass:
    def my_method(self, x: int, y: int) -> int:
        return x + y

def check_signature(obj, method_name, expected_signature):
    method = getattr(obj, method_name)
    signature = inspect.signature(method)
    parameters = signature.parameters

    for param_name, param in parameters.items():
        if param.annotation != expected_signature.get(param_name):
            return False

    return True

# 创建一个实例
obj = MyClass()

# 定义期望的签名注解
expected_signature = {
    'self': MyClass,
    'x': int,
    'y': int,
    'return': int
}

# 检查签名注解是否属于特定类
result = check_signature(obj, 'my_method', expected_signature)
print(result)  # 输出：True
