Question

我正在开展一个简单的项目，我需要一些帮助。我创建了一个在画布上绘制圆圈的程序。圆圈为蓝色，方法flash（）采用随机int计数，并点亮一个圆圈并将其颜色更改为黄色。问题是我希望函数每隔一秒左右继续执行一次，因为我希望最终能够让程序的用户点击被点亮的圆圈，并让程序响应对话框说明正确/不正确用户说得对。截至目前，我只能点亮一个圆圈，就是这样。我尝试使用一个线程并将其设置为每2秒，但这没有用，或者我没有做正确的事情。任何帮助，将不胜感激。

好的，所以你可能想试试这个：把它放在代码的某个地方import time 然后，无论你想要什么延迟，你都可以使用：time.sleep(number of seconds) 您可以通过键入秒数为.1或其他内容来包含毫秒数如果你想让它每隔几秒重复一遍，你就这样做了

while True:
    flash(self,count) #replace self and count with whatever you want
    time.sleep(x) #replace x with amount of seconds, this part is optional though.

while True:使True == True a.k.a.永远循环。如果您只想让它循环一定次数，请执行类似这样的操作

max=6 #6 is the amount of times you want it to loop
loop_count=1 # this is required for later in the loop
while x <=max: #loops ONLY when x is less than or equal to 6
    flash(self,count) #replace self and count with whatever you want
    time.sleep(y) #this part is only if you want it to delay at all.
    loop_count+=1 #this makes it so that every time the loop runs, loop_count gains 1. 
    # after it runs the first time, loop_count == 2 (which means it is starting its second loop)

我希望这对你有意义，我可以提供帮助。如果有任何错误请更正我
