How to take input in Tkinter and then pass it into a function to get the Output

Question

What I want is, that take input from the User through Tkinter. I pass the inputs as an argument to my function and then the function performs itself.

Here is my Code-

import tkinter as tk
from tkinter import *
root=tk.Tk()
root.geometry("644x344")
def getvals(email,date_to,date_from):
    """
    function executes itself 
    """    
Label(root,text="Automatic Email Saver",font="comicansms 13 bold",pady=15).grid(row=0,column=3)
Email = Label(root, text="Email")
date_start = Label(root, text="Starting Date And Time")
date_end = Label(root, text="Ending Date and Time")
Email.grid(row=1, column=2)
date_start.grid(row=2, column=2)
date_end.grid(row=3, column=2)
Emailvalue = StringVar()
date_startvalue = StringVar()
date_endvalue = StringVar()
Emailentry = Entry(root, textvariable=Emailvalue)
date_toentry = Entry(root, textvariable=date_startvalue)
date_endentry = Entry(root, textvariable=date_endvalue)
Emailentry.grid(row=1, column=3)
date_toentry.grid(row=2, column=3)
date_endentry.grid(row=3, column=3)
Button(text="Submit", command=getvals).grid(row=5, column=3)
root.mainloop()

If you really want to pass arguments to your function, check the answers here. But you also have the option of defining getvals with no arguments and within it your vars objects will still be found from the global scope. Or more cleanly, put your window in a class where your vars are stored as attributes and getvals is a method. — Reti43

You need not use any arguments for your function.

Just simply .get() the values.

email = Emailentry.get()
date_to = date_toentry.get()
date_from = date_endentry.get()
