        self.start_time = None
        self.end_time = None

    def start(self):
        self.start_time = time.time()

    def stop(self):
        self.end_time = time.time()

    def elapsed(self):
        return self.end_time - self.start_time

class MyClass:
    def __init__(self):

    def my_method(self):
        self.timer.start()
        # 在这里执行你的代码
        self.timer.stop()
        print(f"my_method执行时间: {self.timer.elapsed()}秒")
