Question

最近在工作中，我编写了一个简短的应用程序来将数据保存在Excel中。仅在不小心按下按钮后出现问题，在输入参数之前先进行确认。然后，空字段保留在工作表中。我知道如何设置按钮活动。我无法创建一种情况，当输入参数时，python“监听”并不断检查条件是否正确。

def okno_wprowadzania_1():

    global temp, day, TiMes, m_Y, wiersz, wilg, master, list, pytanie

    while True:
        TiMe = datetime.datetime.now()
        TiMes = TiMe.strftime("%H:%M")
        if (TiMes == '07:00') or (TiMes == '07:10') or (TiMes == '07:20'):
            wiersz = 7
            day = TiMe.strftime("%d")
            break
        if (TiMes == '10:30') or (TiMes == '10:45') or (TiMes == '11:00'):
            wiersz = 11
            day = TiMe.strftime("%d")
            break
        if (TiMes == '14:30') or (TiMes == '14:45') or (TiMes == '15:00'):
            wiersz = 15
            day = TiMe.strftime("%d")
            break
        if (TiMes == '18:30') or (TiMes == '18:45') or (TiMes == '19:00'):
            wiersz = 19
            day = TiMe.strftime("%d")
            break
        if (TiMes == '22:30') or (TiMes == '22:45') or (TiMes == '23:00'):
            wiersz = 23
            day = TiMe.strftime("%d")
            break
        if (TiMes == '02:30') or (TiMes == '02:45') or (TiMes == '03:00'):
            wiersz = 27
            day = TiMe.strftime("%d")
            print(day)
            korekta = int(day) - 1
            day = korekta
            print(day)
            break

    master=Tk()
    master.protocol("WM_DELETE_WINDOW", on_closing)
    master.title('Wpisz parametry')
    nazwisko=Label(master,text='Pracownik',bg='yellow green')
    nazwisko.pack(fill=X)
    list = Listbox(master,width=40,height=3)
    list.pack(fill=X)
    list.insert(END)
    for item in ['A','M','G']:
        list.insert(END,item)
    temperatura=Label(master,text='Temperatura',bg='yellow green')
    temperatura.pack(fill=X)
    temp=Entry(master)
    temp.pack(fill=X)
    wilgotnosc=Label(master,text='Wilgotność',bg='yellow green')
    wilgotnosc.pack(fill=X)
    wilg=Entry(master)
    wilg.pack(fill=X)
    zamknij=Button(master,text="Zapisz",command=master.quit)
    zamknij.pack(fill=X)

    def answer1():
        answer1 = wilg.get()
        return answer1
    if answer1=='':
        zamknij.configure(state='disabled')
    else:
        zamknij.configure(state='normal')

总结：如果输入字段为空，则该按钮处于非活动状态，输入参数后，该按钮应处于活动状态。该怎么做？

在tkinter中输入参数后如何设置按钮活动？
