如何使用timedelta在两个不同时间之间进行add/subract操作？

Question

所以我想知道这个人会在一天中的什么时候结束运行。在最后一行代码中，尝试使用运算符 addition 时会弹出此错误。我做错了什么？

TypeError: unsupported operand type(s) for +: 'datetime.time' and 'datetime.timedelta'

import datetime
# first run, 1 mile

pace_minutes1 = 8
pace_seconds1 = 15
distance = 1  #1 mile
b = ((pace_minutes1 * 60) + pace_seconds1) * distance
print(b)

# second run, 3 mile
pace_minutes2 = 7
pace_seconds2 = 12
distance = 3  # 3 miles
a = ((pace_minutes2 * 60) + pace_seconds2) * distance
print(a)

# third run, 1 mile run
pace_minutes3 = 8
pace_seconds3 = 15
distance = 1 # 1 mile
c = ((pace_minutes3 * 60) + pace_seconds3) * distance
print(c)

x = (a + b + c)
print(x, "seconds")

time = datetime.timedelta(seconds=x) # converse value "x" seconds to time (h,m,s)
print("All running time will gonna take",time,"seconds") # total time spent running
start_time = datetime.time(6,52,0) # time from where he started running
print("The running started in",start_time)
end_time = (start_time + time) # time when he ended running
print(end_time)

Answer 1

您只能将时间增量添加到 datetime.datetime 对象，而不是 datetime.time 对象（可能是为了避免溢出）。

如此简单的修复，使用 start_time = datetime.datetime(2021, 04, 21, 6,52,0)

Answer 2

请在下面找到答案。检查它是否符合您的要求 desired.May 您可以检查 stack overflow 答案

import datetime
# first run, 1 mile

pace_minutes1 = 8
pace_seconds1 = 15
distance = 1  #1 mile
b = ((pace_minutes1 * 60) + pace_seconds1) * distance
print(b)

# second run, 3 mile
pace_minutes2 = 7
pace_seconds2 = 12
distance = 3  # 3 miles
a = ((pace_minutes2 * 60) + pace_seconds2) * distance
print(a)

# third run, 1 mile run
pace_minutes3 = 8
pace_seconds3 = 15
distance = 1 # 1 mile
c = ((pace_minutes3 * 60) + pace_seconds3) * distance
print(c)

x = (a + b + c)
print(x, "seconds")

time = datetime.timedelta(seconds=x) # converse value "x" seconds to time (h,m,s)
print("All running time will gonna take",time,"seconds") # total time spent running
start_time = datetime.time(6,52,0) # time from where he started running
# print(type(start_time))
# print(type(time))
print("The running started in",start_time)
end_time = (dt.datetime.combine(dt.date(1,1,1),start_time) + time).time()
print(end_time)
