Question

我正在尝试编写一个程序，用户可以输入他们希望它离开多少小时和分钟，然后需要当地时间和小时和分钟，并将两者加在一起以产生时间计划结束。
注意：我不希望它将我的输入和当前时间的数字组合成一个字符串。我需要它来将数字加在一起。

当我运行程序时，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'

我的代码：

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()

Answer 1

如果我已正确理解您的问题，请尝试将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()

Answer 2

time.strftime('%H')已经是整数，但是根据您自己的定义，hour_awake是一个字符串因此TypeError。

Python不执行自动类型转换。你必须自己做。所有操作数（变量）必须与“添加”的类型相同：
- 两个字符串将连接成一个字符串，
- 两个整数将执行算术加法。

您需要通过hour_awake明确地将int(hour_awake)转换为整数然后你应该能够将它们加在一起：

alarm_hour = int(hour_awake) + time.strftime('%H')

和

alarm_minutes = int(minute_awake) + minute

这样您就可以将hour_awake和minute_awake保留为字符串或者，如果您不需要将它们存储为字符串，则将input行更改为：

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

..并为minute_awake做同样的事。

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