How to change a sprites rotation while a button is down [duplicate]

Question

Just started using sprites, figured out how to make it blit, set the image, move with arrow keys, but I don't understand how to rotate it. I've tried some things only nothing seems to work or make sense, Here's my problem. I want the cube figure to rotate 90 degrees while pressing D or moving right, vise-versa for left. Some things have made sense but I still cannot rotate it. Here's my code, any sort of explanation helps, Thanks.

import pygame_textinput
import prompts

pygame.init()
textinput = pygame_textinput.TextInputVisualizer()
black = ("225, 225, 225")
font = pygame.font.SysFont("Comicsansms", 55)

display = pygame.display.set_mode((575, 375))
pygame.display.set_caption("Game")
clock = pygame.time.Clock()
pygame.key.set_repeat(200, 25)

ISSAC = pygame.image.load("issac.png")

class Issac(pygame.sprite.Sprite):
  def __init__(self, image):
    self.image = image
    self.og_img = self.image
    self.x = 0
    self.y = 0
    self.angle = 0
    self.change_angle = 0
    self.rect = self.image.get_rect()
    
  def movement(self):
    key = pygame.key.get_pressed()
    ws = 3
    if key[pygame.K_w]:
      self.y -= ws
    elif key[pygame.K_s]:
      self.y += ws
    if key[pygame.K_a]:
      self.x -= ws
    elif key[pygame.K_d]:
      self.x += ws
      self.change_angle = 90
      
  def draw(self, display):
    display.blit(self.image, (self.x, self.y))
    
  def change(self):
    if self.angle_change != 0:
      self.angle = self.angle_change

issac = Issac(ISSAC)

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()
    issac.movement()
    display.fill((255, 255, 255))
    issac.draw(display)
    pygame.display.update()
    clock.tick(60)```
