我正在嘗試將數(shù)字轉(zhuǎn)換為小時格式，如下所示，numbers = [7,12,16,18]預(yù)期操作：hours = ["07:00 AM","12:00 PM","04:00 PM","06:00 PM"]有沒有辦法實現(xiàn)這一目標？

使用標準庫：
import datetime
numbers = [7, 12, 16, 18]
hours = [datetime.time(num).strftime("%I:00 %p") for num in numbers]
# ['07:00 AM', '12:00 PM', '04:00 PM', '06:00 PM']

嘗試這個：
import datetime
numbers = [7,12,16,18]
hours=[]
for i in numbers:
if i <= 12:
time = str(datetime.timedelta(hours=i)) +" AM"
else:
time = str(datetime.timedelta(hours=i-12)) + " PM"
hours.append(time)
print(hours)
輸出：
['7:00:00 AM', '12:00:00 PM', '4:00:00 PM', '6:00:00 PM']

不是最干凈的方式，但會完成這項工作：
numbers = [7,12,16,18]
hours = []
for n in numbers:
if n < 12:
if len(str(n)) == 1:
temp = "0"+str(n)+":00 AM"
else:
temp = str(n)+":00 AM"
else:
x = n - 12
if x == 0:
temp = "12:00 PM"
if len(str(x)) == 1:
temp = "0"+str(x)+":00 PM"
else:
temp = str(x)+":00 PM"
hours.append(temp)
輸出：
['07:00 AM', '12:00 PM', '04:00 PM', '06:00 PM']
