Python - 计算两个datetime.time对象之间的差异

Question

我有两个datetime.time对象，我想计算它们之间的小时差。例如

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

我希望能够减去这些使得它带给我的价值4

Answer 1

计算差值，您必须将datetime.time对象转换为datetime.datetime对象。然后当你减去，你会得到一个timedelta对象。为了找出timedelta物体有多少小时，您必须找到总秒数并将其除以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
