在python中计算

Question

到目前为止我做了什么：import datetime   distance_tobecovered = float(input("Please enter a number for the startime = input("Please input the time for the alarm in format HH:")    fixed_charge = 3.5    perkilo_charge = 2.1 * distance_tobecovered    valueforall = fixed_charge + perkilo_charge    v = valueforall + (2 * distance_tobecovered * 0.99)

Answer 1

您正在与input_time.hour整数进行比较。没有这样的整数 N 23 <= N <= 6，因此您elif语句中的条件永远不会为真。您应该简单地将elif语句替换为else.

Answer 2

如果您输入的时间为：10:24，则此：datetime.datetime.strptime(startime,"%H:%M") 将起作用。如果您将时间输入为 10，您的示例将起作用。

一切都取决于您如何定义时间输入。

另外，你的比较似乎不对。

import datetime

distance_tobecovered = float(input("Please enter a number for the distance: "))

startime = input("Please input the time for the alarm in format HH:MM :")

fixed_charge = 3.5

perkilo_charge = 2.1 * distance_tobecovered

valueforall = fixed_charge + perkilo_charge

v = valueforall + (2 * distance_tobecovered * 0.99)

input_time = datetime.datetime.strptime(startime, "%H:%M")

if ((input_time.hour>=23) or (input_time.hour < 6)):

    print("night or early morning")

    print(v)#does some calculation

else:

    print("day")

    print("#does some calculation ")
