Coding shapes like a heart using Python's Turtle library is a fun and engaging way to learn programming concepts. With just a few lines of code, we were able to create a simple yet visually appealing drawing. As you embark on this coding adventure, let your creativity bloom like a bouquet...
importasyncioimporttimeimportrandom 然后,我们定义了task_A,其执行时间是随机确定的,可以从1到5秒不等。在执行结束时,如果终止条件没有满足,那么计算就会转到task_B: deftask_A(end_time, loop):print("task_A called") time.sleep(random.randint(0,5))if(loop.time() +1.0) < end_time: loop.call_l...
