[Tkinter] Aligning Python Tkinter Buttons In Rows

[TollyThaWally]

I am trying to make a program in Tkinter where you can press a button and it will add it to a list. I want to align the buttons with **No** text in the box **At All**. I want them in 6 rows of 6, then the 7th row with two in the center. Do you know how I can do this?

My Current Code Is:

from tkinter import *

result = []

def printa():
    result.append('a')
def printb():
    result.append('b')
def printc():
    result.append('c')
def printd():
    result.append('d')
def printe():
    result.append('e')
def printf():
    result.append('f')
def printg():
    result.append('g')
def printh():
    result.append('h')
def printi():
    result.append('i')
def printj():
    result.append('j')
def printk():
    result.append('k')
def printl():
    result.append('l')
def printm():
    result.append('m')
def printn():
    result.append('n')
def printo():
    result.append('o')
def printp():
    result.append('p')
def printq():
    result.append('q')
def printr():
    result.append('r')
def prints():
    result.append('s')
def printt():
    result.append('t')
def printu():
    result.append('u')
def printv():
    result.append('v')
def printw():
    result.append('w')
def printx():
    result.append('x')
def printy():
    result.append('y')
def printz():
    result.append('z')
def printspace():
    result.append('space')
def printperiod():
    result.append('period')
def print0():
    result.append('0')
def print1():
    result.append('1')
def print2():
    result.append('2')
def print3():
    result.append('3')
def print4():
    result.append('4')
def print5():
    result.append('5')
def print6():
    result.append('6')
def print7():
    result.append('7')
def print8():
    result.append('8')
def print9():
    result.append('9')
def printall():
    print(''.join(result))
def clear():
    result = []

root.mainloop()

And every button just appears in one huge list going down.

N.B: I would like to avoid classes if possible, don't worry if it can't be done without.
