1）datetime.datetime.fromtimestamp( tm )

2）datetime.datetime.utcfromtimestamp( tm )

二、datetime->time

1）dt01.timestamp()

2）dt01.timetuple()

演示：

from time import time

from datetime import datetime

time01 = time()

print("轉換前：", time01)

print("轉換後：", datetime.fromtimestamp(time01))

dt01 = datetime.today()

print("轉換前：", dt01)

print("轉換成時間戳：", dt01.timestamp())

print("轉換成時間的元組：", dt01.timestamp())

執行結果：

C:\python\python.exe C:/python/demo/file3.py
