i'm trying send "waves" of enemies code: wavechooser = random.randint(1, 4) print wavechooser if wavechooser == 1: wave1() but when run this, enemies send using wave1() keep flickering. wave1() code runs fine wihtout wavechooser, wavechooser comes problem. i'm guessing because wavechooser in while statement, values of wavechooser keep changing. so question is, how keep enemy opaque? prefer not change if statement because want send multiple waves @ once. wave1() code: def wave1(): global timer global timer1 global angle speed = random.uniform(0.1, 0.9) index = 0 # removing enemies enemy1 in enemies: if enemy1[0] < 330: enemy.pop(index) enemy1[0] -= speed index += 1 enemy1 in enemies: screen.blit(enemy, enemy1) as said, part seems working fine individually. edit: also, after send wave, can't seem able send one. need post more code? edit: of outputted values of wavechooser 3 ...

i confused. understand, piece of code thread-safe if functions correctly during simultaneous execution multiple threads. , data race occurs when 2 instructions different threads access same memory location, @ least 1 of these accesses write , there no synchronization mandating particular order among these accesses. its clear both relate concurrency. addressing same thing? if program(or part) has data race , there high probability program not thread safe . thread-safety declares ultimate property program, uses multithreading. checking property is difficult task , cannot fully performed automatically (because term correctness in multithreaded case badly formalized). data race declares event, (relatively) easy check automatically , , having event has high correlation thread-unsafety . summarized: no data race - program can be thread safe . data race - program unlikely thread safe . some languages prohibit write programs data races. such langu...
