Why does event have no key module? How to change it? #pygame

Question

I am coding a game called the pie game from a book called 'More Python Programming for the Absolute Beginner' but the shapes don't render and a black screen appears.

I want it to display 4 numbers and when you press the keys 1, 2, 3 and 4 on the keyboard, slices of pie/pizza/circular bread/whatever appear (1 arc and 2 lines).

I can't see a problem with the code. Maybe someone has written the same article before, but our code is different.

# @File : piegame.py
# @Software:PyCharm

import math
import sys
import pygame
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((600,500))
pygame.display.set_caption("The Pie Game - Press 1,2,3,4")
myfont = pygame.font.Font(None,60)

color = 200,80,60
width = 4
x = 300
y = 250
radius = 200
position = x-radius,y-radius,radius*2,radius*2

piece1 = False
piece2 = False
piece3 = False
piece4 = False

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
        elif event.type == KEYUP:
            if event.key == pygame.K_ESCAPE:
                sys.exit()
        elif event.key == pygame.K_1:
            piece1 = True
        elif event.key == pygame.K_2:
            piece2 = True
        elif event.key == pygame.K_3:
            piece3 = True
        elif event.key == pygame.K_4:
            piece4 = True

# clear the screen
screen.fill((0,0,200))

# draw the four numbers
testImg1 = myfont.render("1",True,color)
screen.blit(testImg1,(x+radius/2-20,y-radius/2))
testImg2 = myfont.render("2",True,color)
screen.blit(testImg2,(x-radius/2,y-radius/2))
testImg3 = myfont.render("3",True,color)
screen.blit(testImg3,(x-radius/2,y+radius/2-20))
testImg4 = myfont.render("4",True,color)
screen.blit(testImg4,(x+radius/2-20,y+radius/2-20))

#should the pieces be drawn?
if piece1:
    start_angle=math.radians(0)
    end_angle =math.radians(90)
    pygame.draw.arc(screen,color,position,start_angle,end_angle,width)
    pygame.draw.line(screen,color,(x,y),(x,y-radius),width)
    pygame.draw.line(screen,color,(x,y),(x+radius,y),width)

    pygame.draw.arc(screen,color,position,start_angle,end_angle,width)
    pygame.draw.line(screen,color,(x,y),(x,y-radius),width)
    pygame.draw.line(screen,color,(x,y),(x+radius,y),width)

    pygame.draw.line(screen, color, (x, y), (x + radius, y), width)

#is the pie finished?
if piece1 and piece2 and piece3 and piece4:
    color = 0,255,0

pygame.display.update()

Thank you for your comments. The error location is:line 36

elif event.key == pygame.K_1:
    piece1 = True
elif event.key == pygame.K_2:
    piece2 = True
elif event.key == pygame.K_3:
    piece3 = True
elif event.key == pygame.K_4:
    piece4 = True

Why does event have no key module? How to change it? #pygame
