如何定期更新日期时间?
How to update datetime regularly?
我想每秒打印一次日期时间。当我运行
import time, datetime
t0 = time.time()
while True:
print (time.strftime("%H:%M:%S",time.localtime(t0)))
time.sleep(1)
我希望看到这个
20:58:30
20:58:31
20:58:32
20:58:33
20:58:34
等但我得到了这个:
20:58:30
20:58:30
20:58:30
20:58:30
20:58:30
我该怎么做才对?
import time, datetime
while True:
t0 = time.time()
print (time.strftime("%H:%M:%S",time.localtime(t0)))
time.sleep(1)
如果您希望更新发生在同一行:
while True:
sys.stdout.write("\r" + time.strftime("%H:%M:%S",time.localtime(time.time())))
time.sleep(1)
