Python——時間換算

利用datetime模組進行不同時間單位的換算

Python代碼

from datetime import timedelta    a = timedelta(days=2, hours=6)  b = timedelta(hours=4.5)  c = a + b  print(c.days)  print(c.seconds)  print(c.seconds / 3600)

表示特定的日期和時間

Java代碼

from datetime import datetime  a = datetime(2016, 8, 30)  print(a + timedelta(days=10))  b = datetime(2016, 9, 30)  d = b - a  print(d.days)    now = datetime.today()  print(now)  print(now + timedelta(minutes=10))

datetime模組可以正確處理閏年

Java代碼

a = datetime(2012, 3, 1)  b = datetime(2012, 2, 28)  print((a-b).days)  c = datetime(2013, 3, 1)  d = datetime(2013, 2, 28)  print((c-d).days)

處理更為複雜的日期問題，如處理時區，模糊時間範圍，計算節日的日期等可以用dateutil模組
