def countdown():
target_time = datetime.datetime(datetime.datetime.now().year + 1, 1, 1, 0, 0, 0)
while True:
current_time = datetime.datetime.now()
remaining_time = target_time - current_time
if remaining_time.days < 0:
break
hours, remainder = divmod(remaining_time.seconds, 3600)
minutes, seconds = divmod(remainder, 60)
print(f"距离新年还有 {remaining_time.days} 天{hours} 小时 {minutes} 分钟 {seconds} 秒")
time.sleep(1)
print("新年快乐!")
countdown()
```
输出新年快乐:
```python
print("新年快乐!")
```
