Tkinter没有得到可变值

Question

我的Python Tkinter脚本没有获取c，b，a和epoch的变量值，我尝试了其他方法，例如if，function和stuff，但是它不起作用。

我以前从未尝试过Tkinter，所以我很难理解。

def Assis():
    assis = open("ACB/config.ini","w", encoding="utf8") 
    assis.write("State=%s\n" % a)
    assis.write("StartTimestamp=%s\n" % epoch)
    assis.close()

def Come():
    come = open("ACB/config.ini","w", encoding="utf8") 
    come.write("State=%s\n" % c)
    come.write("Details=Comendo\n")
    come.write("StartTimestamp=%s\n" % epoch)
    come.close()

def Bebe():
    bebe = open("ACB/config.ini","w", encoding="utf8") 
    bebe.write("State=%s\n" % b)
    bebe.write("Details=Bebendo\n")
    bebe.write("StartTimestamp=%s\n" % epoch)
    bebe.close()

def ACB():
    count = 0
    while count < 3500:
        Bebe()
        count += 1
        time.sleep(6)
        Come()
        time.sleep(6)
        Assis()
        time.sleep(6)

core = tk.Tk()
core.title("Core.py")
core.geometry("800x700")

def B():
    B2 = tk.Button(core, text ="/AssisComeBebendo", fg="green", command=C)
    B2.pack()

def C():
    choice = "yes"
    if choice == "yes":
        label = Label(core, text="\nAssisComeBebendo: \nTime:")
        btn1 = Text(core, bg="white", fg="black", width="10", height="1")
        label.pack()
        btn1.pack()
        webbrowser.open("https://www.epochconverter.com/clock")
        label = Label(core, text="\nComendo:")
        btn2 = Text(core, bg="white", fg="black", width=lar, height="1")
        label.pack()
        btn2.pack()
        label = Label(core, text="\nBebendo:")
        btn3 = Text(core, bg="white", fg="black", width=lar, height="1")
        label.pack()
        btn3.pack()
        label = Label(core, text="\nAssistindo:")
        btn4 = Text(core, bg="white", fg="black", width=lar, height="1")
        label.pack()
        btn4.pack()
        B2 = tk.Button(core, text ="/Rodar 2", fg="green", command=ACB)
        B2.pack()
        epoch = btn1.get("1.0","end-1c")
        c = btn2.get("1.0","end-1c")
        b = btn3.get("1.0","end-1c")
        a = btn4.get("1.0","end-1c")
        print(b)

B()

core.mainloop()

也许我应该使用全局变量或尝试在UI之外定义它，我不知道
