以十二小時(上午、下午)顯示現在時刻。
```python
import datetime
# 取得當前時間
now = datetime.datetime.now()
# 將24小時制轉換為12小時制
formatted_time = now.strftime("%I:%M %p") # %I: 小時(12小時制), %M: 分鐘, %p: 上午或下午
print("現在時刻是:", formatted_time)
```
現在時刻是: 11:34 AM
```python
import time as t
time1 = t.localtime()
show = "現在時刻:"
if time1.tm_hour < 12:
show += "上午 "
hour = time1.tm_hour
else:
show += "下午 "
hour = time1.tm_hour - 12
show += str(hour) + " 點 " + str(time1.tm_min) + " 分 "
show += str(time1.tm_sec) + " 秒"
print(show)
