不要在特定时间（例如1小时）内再次运行python脚本

Question

我正在使用这个python脚本： LINK

到目前为止效果很好。 但现在我想对它进行优化，因为有时脚本会在10-20分钟内执行2-3次，因为如果有3个或更多流（例如4个流），它将始终运行。流将启动-->；通知将再次发送，或者如果用户决定取消此流并观看另一部电影-->；脚本将再次运行！）你知道吗

我试过使用time.sleep，但那不起作用。我想要这样的：

如果程序将被执行，它不应该在接下来的60分钟内再次运行。你知道吗

我需要在这里使用什么/代码？你知道吗

谢谢你的帮助！你知道吗

谢谢你的提示，我的代码现在看起来是这样的（你能检查一下吗？）地址：

让脚本将时间戳写入外部文件，并在启动时检查该文件。你知道吗

举个例子：

import time

def script_has_run_recently(seconds):
    filename = 'last-run-time.txt'
    current_time = int(time.time())
    try:
        with open(filename, 'rt') as f:
            last_run = int(f.read().strip())
    except (IOError, ValueError) as e:
        last_run = 0
    if last_run + seconds > current_time:
        return True
    else:
        with open(filename, 'wt') as f:
            f.write(str(current_time))
        return False


def main():
    print('running the main function.')


if __name__ == "__main__":
    seconds = 3600  # one hour in seconds
    if script_has_run_recently(seconds):
        print('you need to wait before you can run this again')
    else:
        main()
