title: How do I get an entry widget to save what I input? Python Tkinter
body: <p>I want to make an entry widget that inputs personal details, however I want to save those details as variables, so I can write them in a txt file. </p>
  
  <pre><code>from tkinter import *
  root = Tk()
  Label(root, text = "Childs First name").grid(row = 0, sticky = W)
  Label(root, text = "Childs Surname").grid(row = 1, sticky = W)
  Label(root, text = "Childs Year of Birth").grid(row = 2, sticky = W)
  Label(root, text = "Childs Month of Birth").grid(row = 3, sticky = W)
  Label(root, text = "Childs Day of Birth").grid(row = 4, sticky = W)
  
  Fname = Entry(root)
  Sname = Entry(root)
  x = Entry(root)
  y = Entry(root)
  z = Entry(root)
  
  
  Fname.grid(row = 0, column = 1)
  Sname.grid(row = 1, column = 1)
  x.grid(row = 3, column = 1)
  y.grid(row = 2, column = 1)
  z.grid(row = 4, column = 1)
  
  Fname = Fname.get
  Sname = Sname.get
  x = x.get
  y = y.get
  z = z.get
  mainloop()
  </code></pre>
  
  <p>My code works absolutely fine, however it doesn't save what I inputted, let alone save it within a variable. I'm obviously missing chunks of code, but I don't know what code.</p>
  
  <p>P.S: Also, if it's not too much, how would I make a button to continue on to the next lines of code?</p>
