Python 错误：TypeError：+ 不支持的操作数类型：'int' 和 'str'

我正在尝试编写一个程序，用户可以输入他们希望它关闭的小时和分钟，然后，它需要当地时间以及小时和分钟，然后将两者加在一起以产生程序运行的时间离开。
注意：我不希望它将我的输入和当前时间的数字作为字符串放在一起。我需要它来将数字加在一起。

当我运行该程序时，我收到此错误：

line 30, in alarm_time   
  alarm_hour = (hour_awake + time.strftime('%H'))
TypeError: unsupported operand type(s) for +: 'int' and 'str'

My Code:

from tkinter import *
import tkinter
import time

time_now = ''

hour = time.strftime("%H")
minute = time.strftime("%M")

str(hour)
str(minute)



def tick():
    global time_now
    time_now = time.strftime("%H:%M:%S")



def hours():
    global hour_awake
    hour_awake = str(input("please enter in how many hours you would like to have the alarm go off in. "))
    minutes()

def minutes():
    global minute_awake
    minute_awake = str(input("please enter in how many minutes you would like to have the alarm go off in. "))

def alarm_time():
    alarm_hour = (hour_awake + hour)
    alarm_minutes = (minute_awake + minute)
    print (alarm_hour, alarm_minutes)


tick()

hours()
alarm_time()

如果我正确理解了你的问题，那么尝试将你的 str() 更改为 int() ，如下所示：

from tkinter import *
import tkinter
import time

time_now = ''

hour = time.strftime("%H")
minute = time.strftime("%M")

int(hour)
int(minute)



def tick():
    global time_now
    time_now = time.strftime("%H:%M:%S")



def hours():
    global hour_awake
    hour_awake = int(input("please enter in how many hours you would like to have the alarm go off in. "))
    minutes()

def minutes():
    global minute_awake
    minute_awake = int(input("please enter in how many minutes you would like to have the alarm go off in. "))

def alarm_time():
    alarm_hour = (hour_awake + hour)
    alarm_minutes = (minute_awake + minute)
    print (alarm_hour, alarm_minutes)


tick()

hours()
alarm_time()
