Python - 計算兩個datetime.time對象之間的差異

Question

我有兩個datetime.time對象，我想計算它們之間的小時差。例如

a = datetime.time(22,00,00) 
b = datetime.time(18,00,00) 

我希望能夠減去這些使得它帶給我的價值4

Answer 1

計算差值，您必須將datetime.time對象轉換爲datetime.datetime對象。然後當你減去，你會得到一個timedelta對象。爲了找出timedelta物體有多少小時，您必須找到總秒數並將其除以3600。

# Create datetime objects for each time (a and b) 
dateTimeA = datetime.datetime.combine(datetime.date.today(), a) 
dateTimeB = datetime.datetime.combine(datetime.date.today(), b) 
# Get the difference between datetimes (as timedelta) 
dateTimeDifference = dateTimeA - dateTimeB 
# Divide difference in seconds by number of seconds in hour (3600) 
dateTimeDifferenceInHours = dateTimeDifference.total_seconds()/3600
