python - 将时间与值(value)进行比较

Question

我有来自 Tkinter Spinbox 的值

       e1 = Spinbox(window, from_=0, to=23, width= 3, state = 'readonly')
       e2 = Spinbox(window, from_=0, to=59, width= 3, state = 'readonly')
       e3 = Spinbox(window, from_=0, to=23, width= 3, state = 'readonly')
       e4 = Spinbox(window, from_=0, to=59, width= 3, state = 'readonly')

我使用此代码通过 insrt() 函数的 return 从 spinbox 获取变量

        time_func = insrt() #takes variables from Tkinter out

        first = time_func[0]
        first = int(first)
        second = time_func[1]
        second = int(second)
        third = time_func[2]
        third = int(third)
        fourth = time_func[3]
        fourth = int(fourth)

并将其插入变量morning，这是time函数

        morning = time.strftime("%d:%d" %(first, second))
        evening = time.strftime("%d:%d" %(third, fourth))

但它返回类似这样的内容:“3:5”(3 小时 5 分钟)

我想将它与 time.time(now) 进行比较，我不想使用 datetime 因为我想在定义的日期和 中进行比较>datetime 不能很好地配合它

        now = time.strftime("%H:%M", time.localtime(time.time()))

我正在使用time_in_range函数进行比较

def time_in_range(morning, evening, x):
    if morning <= evening:
        return morning <= x <= evening
    else:
        return morning <= x or x <= evening
timerange = time_in_range(morning, evening, now)

如果相同则返回 True，否则返回 False。但有一个小问题，morning 是这样的 3:5 而 now 变量是这样的 03:05 code> 所以它根本不匹配，因为那个零，我能做些什么来正确地编译它？这是完整的代码

import sys

import datetime

# Function for Tkinter to associate variables
def insrt():
    element_1 = e1.get()
    element_2 = e2.get()
    element_3 = e3.get()
    element_4 = e4.get()

    return (element_1, element_2, element_3, element_4)

# Function for closing Tkinter window with button
def close_window ():
    window.destroy()

# Creating Tkinter first window and lines and labels
window = Tk()

Label(window, text=" 終わりの時間（分）").grid(row=5)

e1 = Spinbox(window, from_=0, to=23, width= 3, state = 'readonly')
e2 = Spinbox(window, from_=0, to=59, width= 3, state = 'readonly')

e1.insert(2,"")

mainloop() # End of first Tkinter window


#setting used variables for main function
time_func = insrt() # Calling for the function (associated vars)
first = time_func[0] #Taking first number from time_func
first = int(first) #converting for the strftime

second = int(second)
third = time_func[2]
third = int(third)
fourth = time_func[3]
fourth = int(fourth)
fifth = time_func[4]
six = time_func[5]
six = int(six)


now = time.strftime("%H:%M", time.localtime(time.time())) # time now
morning = time.strftime("%d:%d" %(first, second)) # start time for the time function(inserting value)
evening = time.strftime("%d:%d" %(third, fourth)) # end time for the time function(inserting value)

def time_in_range(morning, evening, x):
    if morning <= evening:
        return morning <= x <= evening
    else:
        return morning <= x or x <= evening


while True:
    timerange = time_in_range(morning, evening, now)
    if timerange != True:
        print("Waiting for the right time")
        sleep(200)
    else:
        print("do something else")

我发现与datetime模块进行比较更容易。您所需要做的就是通过 datetime.now() 获取当前时间，然后通过替换构建您的早上/晚上时间。

def compare_time():
    ...
    now = datetime.now()
    morning = now.replace(hour=int(first),minute=int(second))
    evening = now.replace(hour=int(third), minute=int(fourth))

然后您可以直接在所有 3 个之间进行比较。

此外，如果您选择 OOP 方法，您的代码可以大大缩短:

from datetime import datetime
from tkinter import *

class MyGui(Tk):
    def __init__(self):
        Tk.__init__(self)
        self.title("監視システム")
        self.boxes = []
        labels = (" スタート時間（時）"," スタート時間（分）",
                  " 終わりの時間（時）"," 終わりの時間（分）")

        for num, label in enumerate(labels,2):
            s = Spinbox(self, from_=0, to=23 if not num%2 else 59, width=3, state='readonly')
            Label(self,text=label).grid(row=num)
            s.grid(row=num,column=1)
            self.boxes.append(s)

        # Tkinter buttons
        Button(self, text='  Start  ', command=self.compare_time).grid(row=7, column=1, sticky=E, pady=4) #スタート
        Button(self, text=" 閉じる ", command=self.destroy).grid(row=7, column=0, sticky=W, pady=4)

    def compare_time(self):
        first, second, third, fourth = [i.get() for i in self.boxes]
        now = datetime.now()
        morning = now.replace(hour=int(first),minute=int(second))
        evening = now.replace(hour=int(third), minute=int(fourth))
        print (f"Current time: {now}, Morning time: {morning}, Evening time: {evening}")
        # do the rest of your time_in_range stuff here

root = MyGui()

root.mainloop()
