You guys don't need all the config() calls, you can place them within the constructor if you want. I like to add comments line-by-line for teaching purposes to help explain. Do what works for you.

Python Tkinter GUI entry widget for user input tutorial for beginners

# entry widget = textbox that accepts a single line of user input

from tkinter import *

def submit():
username = entry.get() #gets entry text
print("Hello "+username)

def delete():
entry.delete(0,END) #deletes the line of text

def backspace():
entry.delete(len(entry.get())-1,END) #delete last character

window = Tk()
window.title("user input")
label = Label(window,text="username: ")
label.config(font=("Consolas",30))
