python - 在python中减去两次

Question

我的代码有问题。我试图减去两次，但它给了我一个错误:

TypeError: unsupported operand type(s) for -: 'time.struct_time' and 'time.struct_time'

错误在这条线上跳跃:

diff = (end_dt - start_dt)

当我尝试这个时:

start = "09:35:23"
end = "10:23:00"
start_dt = time.strptime(start, '%H:%M:%S')
end_dt = time.strptime(end, '%H:%M:%S')
diff = (end_dt - start_dt)

你能帮我解决我遇到的错误吗？

Answer 1

您需要使用 datetime模块:

import datetime

start = "09:35:23"
end = "10:23:00"
start_dt = datetime.datetime.strptime(start, '%H:%M:%S')
end_dt = datetime.datetime.strptime(end, '%H:%M:%S')
diff = (end_dt - start_dt)
print(diff)

输出

datetime.timedelta(0, 2857)

这会生成两个 datetime对象， start_dt和 end_dt .当您从另一个中减去一个时，它会返回 timedelta .
