The WASD Controls for an image in my game not working

Question

The WASD Controls for an image in my game aren't working, but in the same project there is a part of the code where it makes the sprite move to the mouse pointer. Why does WASD controls not work?

Help would be much appreciated, Antoni

I tried figuring out why their were errors with the modules i imported, and i tried to arrange the code differently [PLEASE NOTE THIS IS AN UPDATED QUESTION AND CODE IS NEW]

Code below

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

spaceship = ('sprite.png')
mouse_c = ('crosshair.png')
backg = ('background.jpg')
pygame.init()
screen = pygame.display.set_mode((800, 600))
bk = pygame.image.load(backg).convert_alpha()
mousec = pygame.image.load(mouse_c).convert_alpha()
space_ship = pygame.image.load(spaceship).convert_alpha()
clock = pygame.time.Clock()
pygame.mouse.set_visible(False)
while True:
  for event in pygame.event.get():
    if event.type == QUIT:
      pygame.quit()
      sys.exit()
    elif event.type == MOUSEBUTTONDOWN and event.button == 1:
      print("test1")
    elif event.type == MOUSEBUTTONDOWN and event.button == 3:
      print("test3")
    screen.blit(bk, (0, 0))
    pos = pygame.mouse.get_pos()
    screen.blit(mousec, (pos))
    angle = 360-math.atan2(pos[1]-300,pos[0]-400)*180/math.pi
    rotimage = pygame.transform.rotate(space_ship,angle)
    rect = rotimage.get_rect(center=(400,300))
    screen.blit(rotimage,rect) 
  #I need space_ship to rotate towards my cursor
    pygame.display.update()

  pygame.display.set_caption('Player Movement')
  
# Initializing the clock

    # that was returned by pygame.event.get() method.

        # Closing the window and program if the
        # type of the event is QUIT
    if event.type == pygame.QUIT:
      run = False
      pygame.quit()
      quit()
  
    # Storing the key pressed in a
    # new variable using key.get_pressed()
    # method

while True:
