i working on simple project , need little help. have created program draws circles on canvas. circles blue, , method flash() takes random int count, , light circle , change color yellow. problem want function continue execute every second or so, because want able let user of program click onto circle lit, , have program respond dialog stating correct/incorrect if user got right. of right can light 1 circle , it. tried using thread , set every 2 seconds, didn't work or maybe didn't correctly. appreciated.

okay, may want try this: put in code somewhere in beginning import time then, ever want delay, use this:time.sleep(number of seconds) can include milliseconds in typing amount of seconds .1 or if want repeat every few seconds, this

while true:     flash(self,count) #replace self , count whatever want     time.sleep(x) #replace x amount of seconds, part optional though. 

the while true: makes loop while true == true a.k.a. forever. if want loop amount of times, this

max=6 #6 amount of times want loop loop_count=1 # required later in loop while x <=max: #loops when x less or equal 6     flash(self,count) #replace self , count whatever want     time.sleep(y) #this part if want delay @ all.     loop_count+=1 #this makes every time loop runs, loop_count gains 1.      # after runs first time, loop_count == 2 (which means starting second loop) 

i hope made sense , help. if there errors please correct me
