Python是－時間換算

利用datetime模組進行不同時間單位的換算

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  

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 ，計算節日的日期等可以用dateutil模組
