场景：希望持续执行脚本5秒钟
问题：程序未执行完，退出了
描述：以下两种方法都试过，都是同样的现象，不知道啥情况，希望大佬们能帮忙解答一下，谢谢！
源码：
def test_time(self):
start_run_time = datetime.datetime.now()
end_run_time = start_run_time + datetime.timedelta(seconds=5)
print(f'start_run_time:{start_run_time}')
print(f'end_run_time:{end_run_time}')
i = 0
while True:
if start_run_time <= end_run_time:
print(f"第{i}次打印")
i = i + 1
print(f'循环打印后的i为：{i}')
start_run_time = datetime.datetime.now()
print(f'循环后的时间：{start_run_time}')
else:
break
print(f'跳出循环后的i：{i}')
print(f'跳出循环后的时间：{start_run_time}')
def test_time2(self):
end = int(time.time()) + 5
print(f"start-time:{int(time.time())}")
print(f"start-time:{end}")
j =0
while (int(time.time()) <= end):
print(f"working:{j}")
j=j+1
print(f"当前循环后的time:{int(time.time())}")
print(f"最终循环后的j:{j}")
print(f"最终循环后的time:{int(time.time())}")
