How to obtain all available Entry values

Question

I have created a pop up that would ask for entry, and the amount of entries would depend on the information given.

self.e = Entry(self.top, bd = 5)
self.e.grid(column = 1, row = 0)
row = 2
for d in extra:
   self.e2 = Entry(self.top, bd = 5)
   self.e2.grid(column = 1, row = row)
   row = row + 1

def ok(self):
   new = self.e.get().strip()

Function ok would be called by a button and then it would return the values. How do I return a list of values from an unknown amount of entries?

Answer 1

Normally, you would put the entries in a list:

from Tkinter import *

class App(object):

    def __init__(self, top):
        self.top = top
        self.ok_button = Button(self.top, text='OK', command=self.ok)
        self.make_entries()

    def make_entries(self): 
        self.entries = []
        for d in extra:
            e2 = Entry(self.top, bd = 5)
            e2.grid(column = 1, row = row)
            self.entries.append(e2)
            row += 1

    def ok(self):
        values = [e.get().strip() for e in self.entries]

root = Tk()
app = App(root)
root.mainloop()
