所以我和我堂兄一起编写了一个小项目，但由于我们没有Python 3.x的经验，我们无法为我可以购买的其中一个项目创建一个后台循环。店。我是唯一一个在多线程方面有一点经验的人（请注意，我几乎不知道任何事情），所以我到处寻找解决方案，我没有这样做。到目前为止，这是我的代码：

player_value = player_value+10000
def scav_loopJob(worker):
while True:

time.sleep(1)
def threader():
while True:

cap_scavengerJob(worker)
q.task_done()
def threader():

我真正需要帮助的是如何同时运行主程序和scav_loop，我还需要了解多线程XD的某些方面。任何帮助表示赞赏！
答案 0 :(得分：0)
如果你是Python新手，不确定你需要的是背景循环你最好用数学来模拟时间，但是，这是我个人的观点。我允许自己检查/重写你的代码，因为我发现了一些错误，比如没有遵循PEP8规则，或者出现了错误的if/elif/elif/elif块等...
我的主张远非完美，但应该开始帮助你以更好的方式组织自己。确保您的代码可读，保持您的变量正确命名，保持您的方法正确命名，明天就能自己阅读。
希望有所帮助。

1) Trying to use 'input' from like 20 thread simultaneously is probably
not a great idea.
2) You should read the PEP8
3) Good thing you're using Python 3 :-)
4) You should write shorter methods, aroudn 25 lines max
5) Why do you need background tasks ?
If you think you need background tasks to increment a variable each
second, that's probably not the easier way to start. A good may may
probably better to "simulated" this, like storing the last time the
player have seen its credits, computing the number of seconds since
then, and adding it just before printing again.
Don't forget to drop a line or two of doc to explain what you're
doing.
