python的stdout是有缓冲区的，给你个例子你就知道了 import timeimport sysfor i in range(5): print i, #sys.stdout.flush() time.sleep(1)这个程序本意是每隔一秒输出一个数字，但是如果把这句话sys.stdout.flush()注释的话，你就只能等到程序执行完毕，屏幕上会一次性输出0，1，2，...
方法A:使用flush刷新输出数据到终端。 import sys import time for i in range(10): print(i,end=' ') sys.stdout.flush() time.sleep(1) 方法B:print中flush为True。 import sys import time for i in range(10): print(i,end=' ',flush=True) time.sleep(1) 三 总结备忘 flush应用在需要实时...
