how can I return the user input from entry widget in tkinter

Question

I have this simple problem with this code. the purpose is to make a label showing whatever the user has typed in the Entry widget.

def action():

    output = tk.Label(master, text = #this should be the user input in the Entry widget)
    output.grid(row=2)

import tkinter as tk

master = tk.Tk()

e = tk.Entry(master, bg = 'orange').grid(row=0)
b = tk.Button(master, text = 'do it', bg = 'white', command = action).grid(row = 1)

master.mainloop()

You Have to Define variable of StringVar. then pass it through Entry widget initialization and then you can get text of the widget by setting get function for StringVar variable. here is the code.

content = StringVar()
entry = Entry(parent, text=caption, textvariable=content)

# Getting Text from Entry Widget
text = content.get()

# Setting text to Entry widget
content.set(text)

you can read documentation here : https://effbot.org/tkinterbook/entry.htm

You don't have to use a StringVar. You can, but it's quite possible to get and set the text in a label or entry without it.
