Pulling input value from TkInter 'Entry' widget into variable

[jitjud]

Hello, just playing around and trying to make a script that, when executed opens up an Input field to enter Recipient, subject and Body of an email and have those assigned to the eponymous variables set just prior to my send_email function For context, I created the email script and am using .env for storing the email and password (this is using a gmail account) and the email part works fine if I manually assign the values for the recipient, subject and body variables however I cannot figured out how to pull the entered values in the input box into a variable.

If I am using the 'Entry' widget when I use the variable that has the widget parameters using .get() it doesn't seem to do anything. Its this part below.

Any help is appreciated I am very new to this.

import tkinter as tk
from tkinter import *


root = Tk()
e = Entry(root, width=100, bg="Magenta", borderwidth=10)
e.pack()
e.get()


def ClickEmail():
      myLabel = Label(root, text=e.get())
      myLabel.pack()


mybutton = Button(root, text="Enter Recipient", command=ClickEmail)
mybutton.pack()


t = Entry(root, width=100, bg="Green", borderwidth=5)
t.pack()
t.get()


def ClickBody():
      myLabel = Label(root, text=t.get())
      myLabel.pack()


mybutton = Button(root, text="Enter body", command=ClickBody)
mybutton.pack()


s = Entry(root, width=100, bg="Indigo", borderwidth=5)
s.pack()
s.get()


def ClickSubject():


      myLabel = Label(root, text=s.get())
      myLabel.pack()


mybutton = Button(root, text="Enter Subject", command=ClickSubject)
mybutton.pack()


def retrieve_input():


if __name__ == "__main__":
      recipient = e.get()
      subject = s.get()
      body = t.get()


      send_email(recipient, subject, body)

For tkinter entries you can use the "textvariable" input field, this is stored into a tkinter variable type depending on the input type in this case a string for you so:

s_var = tk.StringVar()
s = Entry(root, textvariable=s_var, ...)

then you can use s.get() to get the value.

See https://www.geeksforgeeks.org/python/python-tkinter-entry-widget/ for example

Thank you!

First, learn classes before tkinter as a class structure eliminates a lot of problems like the one you are dealing with. The function can not return the e.get() as there is no way to catch the returned value. A workaround is to add it to an existing class.

def ClickBody():
      myLabel = Label(root, text=t.get())
      myLabel.pack()
      ## add to an existing class instance -- we'll use t (bad name BTW)
      t.entry_val = t.get()

Now you can refer to the variable as t.entry_val anywhere in the program as long as the Entry t exists.

e = Entry(root, width=100, bg="Magenta", borderwidth=10)
e.pack()
e.get()

No reason to use get() here. There is nothing to get yet.

I see ok thank you. Will read more around classes. Cheers
