python2.7 如何实现不断从entry获取entry.get()并存储

代码如下 能否通过button实现
from Tkinter import *
master = Tk()
e = Entry(master)
e.pack()
e.focus_set()
def clr_text():
e.delete(0, END)
def callback():
n = e.get()
def list_n():
a = []
print a

b1 = Button(master, text="get", width=10, command=callback)
b1.pack()
b2 = Button(master, text="clear", width=10, command=clr_text)
b2.pack()
b3 = Button(master, text="comfirm", width=10, command=list_n)
b3.pack()
mainloop()

from Tkinter import *

master = Tk()

e = Entry(master)

e.pack()

e.focus_set()

a=[]

global a

def clr_text():

    e.delete(0, END)

    #a.pop()删除最后一个元素

def callback():

    n = e.get()

    a.append(n)

def list_n():

    print a

b1 = Button(master, text="get", width=10, command=callback)

b1.pack()

b2 = Button(master, text="clear", width=10, command=clr_text)

b2.pack()

b3 = Button(master, text="comfirm", width=10, command=list_n)

b3.pack()

mainloop()
