Suggest how can I for loop runs for i=0 to i=9, each time initializing i with the value 0 to 9. when i = 3, above condition executes, does the operation i=i+1 and then continue, which looks to be confusing you, so what continue does is it will jump the execution to start the next iteration without executing the code after it in the loop, i.e. I have try stop with Pygame event and pygame.quit WebExample 1: python for loop increment #you can specify incremental values for for loops in python too!
