Python线程和多循环问题

Question

所以我创造了一个游戏，你买气球，你买的越多，你赚的越多。要做到这一点，我需要帮助添加金钱，问题是我需要两个循环，一个在无限循环上，另一个在计时器循环上。我通过线程完成了这两个循环。我打印了一些文本来测试它们是否有效。如果他们像我希望的那样工作，它应该做一个无限循环，他们两个永远都会去Loop1 Loop2 Loop1 Loop2 Loop1 Loop2

但是它只做了Loop1 Loop2一次，这表明它不是无限循环的。这是我的源代码，有点乱，但那是因为我是新手

谢谢你的帮助，非常感谢。

当你的主线程退出时，线程停止运行。在您的程序中，您启动了两个新线程，但不要让主线程等待它们完成工作。

尝试将.join()调用添加到您的主脚本：

thread1.join()
thread2.join()

另外，如果你想要"Loop1 Loop2 Loop1 Loop2..."，你的loop2函数也需要一个无限循环。
