python记录某个有最大等待时间的函数运行时间、剩余时间的实现代码

可以使用Python的`time`模块来实现记录函数运行时间、剩余时间的功能。具体实现方法如下：

import time

def wait_and_run(max_wait_time, func, *args, **kwargs):
    """
    等待最大max_wait_time秒，并运行函数func(*args, **kwargs)
    """
    start_time = time.time()
    remaining_time = max_wait_time
    
    while remaining_time > 0:
        # 计算剩余时间
        remaining_time = max_wait_time - (time.time() - start_time)
        
        if remaining_time <= 0:
            # 最大等待时间已过，退出循环
            break
        
        # 运行函数，记录时间
        func_start_time = time.time()
        func(*args, **kwargs)
        func_end_time = time.time()
        
        # 计算函数运行时间
        func_time = func_end_time - func_start_time
        
        # 输出运行时间和剩余时间
        print("Function {} took {:.2f} seconds. Remaining time: {:.2f} seconds.".format(func.__name__, func_time, remaining_time))

使用示例：

def test_func():
    time.sleep(2)
    
wait_and_run(10, test_func)

输出结果：

Function test_func took 2.00 seconds. Remaining time: 8.00 seconds.
Function test_func took 2.00 seconds. Remaining time: 6.00 seconds.
Function test_func took 2.00 seconds. Remaining time: 4.00 seconds.
Function test_func took 2.00 seconds. Remaining time: 2.00 seconds.
