Get contents of a Tkinter Entry widget

Question

I am creating an application and I want to use the entered values in the GUI Entry widget.

How do I get the entered input from a Tkinter Entry widget?

root = Tk()
...
entry = Entry(root)
entry.pack()

root.mainloop()

Answer 1

You need to do two things: keep a reference to the widget, and then use the get() method to get the string.

Here's an example:

self.entry = Entry(...)
...
print("the text is", self.entry.get())

Answer 2

Here's an example:

import tkinter as tk

class SampleApp(tk.Tk):

    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.button = tk.Button(self, text="Get", command=self.on_button)
        self.button.pack()
        self.entry.pack()

    def on_button(self):
        print(self.entry.get())

w = SampleApp()
w.mainloop()

Answer 3

First declare a variable of required type. For example an integer:

var = IntVar()

Then:

entry = Entry(root, textvariable=var)

entry.pack()

user_input = var.get()

root.mainloop()

Hope this helps.
