各位大佬好，本人是个无基础的萌新...如果有基础错误请各位不吝赐教，拜谢。
需求是做一个GUI界面，展示两个label，一个text，一个entry，一个button。通过点击button获取ertry中的值并进行判断，结果输出在text中。
目前问题是，GUI的界面可以正常展示，但是执行自定义的方法时，脚本没有任何反应就结束了....附代码如下：

from tkinter import *
from datetime import *

root = Tk()
root.title('请假小程序')
holiday=["seek","year","others"] #定义假期类型
seek=12 #初始化假期时间
seekholiday=[]
year=15 #初始化假期时间
yearholiday=[]
othersholiday=[]
e=StringVar()
tapin = Entry(root,textvariable=e)
Texta=Text(root)
Label(root,text="命令输入框：").grid(row=0)
Label(root,text="结果显示:").grid(row=1)
tapin.grid(row=0,column=1)
Texta.grid(row=1,column=1)

Texta.insert(INSERT,('今日日期为:', '\n',date.today()))
Texta.insert(END, '\n请病假/请年假/请其他假/查看请假记录/退出？')

def getvalue():
    e=tapin.get()
    while e != '退出':
        if e == '请病假':
            seek -= 1
            seekholiday.append(date.today())
            Texta.insert(END, "\n当前剩余病假为：", seek)
            continue

        elif e == '请年假':
            year -= 1
            yearholiday.append(date.today())
            Texta.insert(END, "\n当前剩余年假为：", year)
            continue

        elif e == '请其他假':
            othersholiday.append(date.today())
            Texta.insert(END, "\n已记录本次请假")
            continue

        elif e== '查看请假记录':
            Texta.insert(END, "\n当前剩余病假为：", seek, '\n')
            Texta.insert(END, "\n病假记录为：", seekholiday, '\n')
            Texta.insert(END, "\n当前剩余年假为：", year, '\n')
            Texta.insert(END, "\n年假记录为：", yearholiday, '\n')
            Texta.insert("\n其他请假记录为：", othersholiday, '\n')
            continue

        elif e=='退出':
            Texta.insert(END,"\nGoodbye")
            root.mainloop()

        else:
            Texta.insert(END,"\n不正确的命令")
            continue

button1 = Button(root, text="确认", command=getvalue())
button1.grid(row=0, column=2)

button1 = Button(root, text="确认", command=getvalue)
button1.grid(row=0, column=2)
root.mainloop()

改了一些地方.你自己对照着看吧

万分感谢！

我这就去学习学习，太谢谢啦
