tkinter将值从列表显示到条目小部件

Question

Using tkinter in the gui I'm building an array made of entry boxes. In some columns of the array I'm entering values which i read them and build a list for every column. There are also columns without values which are readonly in which I want to export results from lists. I can't find how to make the program to show the results.

Keep in mind that i have two defs one for building the widgets and one for the calculations.

In order to build one empty-results column I make this:

self.akt_b =[]
    for i in range(12):
        akt_b =StringVar()
        self.akt_b =Entry(self, textvariable =akt_b, width =10,
                                  state='readonly', readonlybackground ="white")
        self.akt_b.grid(row =7+i, column =3)

which makes visually what I want. Then I calculate a list_b of 12 float numbers which I want to show in self.akt_b I'm trying:

for i in range(12):
        self.akt_b[i+1].delete(0, END)
        self.akt_b[(i+1)].set("round(list_b[(i+1)], 2)")

which doesn't work I've tried also .insert not again, I've tried akt_b nothing again

what can I do?

Answer 1

after Kevin's answer I found out the solution, I was missing the .append argument.

Just in case anyone is interested here is the solution:

self.akt_b, self.entries =[], []
    for i in range(12):
        akt_b =StringVar()
        entries =Entry(self, textvariable =akt_b, width =10,
                                  state='readonly', readonlybackground ="white")
        entries.grid(row =7+i, column =3)
        self.akt_b.append(akt_b)

so now

for i in range(12):
      self.akt_b[i].set(round(list_b[i], 2))

works perfect.
