Question

我有两个二维数组列表。在一个列表（a）中，我有Tkinter条目的数组。在另一个（b）中，我使用.get（）读入条目。由于某种原因，（b）中的所有二维数组都被最后一个索引数组覆盖（从a读取）。需要单独的对象来防止这种情况吗？这是我的代码：

from Tkinter import *
import ttk
print "\n"

def create_grid(x, y, data=None): # x is rows, y is columns

    empty = [None] * x # if coordinates not needed
    for i in range(x):
        empty[i] = [None] * y


    if data == 1: # if coordinates needed, adds in pairs
        for i in range(x):
            for j in range(y):
                empty[i][j] = [None] * 2



    return empty

def process(event):
    global a
    global b
    global c

    for i in range(2):
        for j in range(2):
            for k in range(2):
                b[i][j][k] = a[i][j][k].get()

    print b

w = Tk()
w.wm_title("test")


a = [create_grid(2,2)] * 2
b = [create_grid(2,2)] * 2


for i in range(2):
    for j in range(2):
        for k in range(2):
            a[i][j][k] = Entry(w)
            a[i][j][k].grid(row=(2*i)+j, column=k)

button = Button(w, text="process")
button.grid(row=8, column = 0, columnspan = 2)
button.bind("<Button-1>", process)


w.mainloop()

Entries and the resulting output

Python Tkinter。 python数组中的条目被覆盖
