[Python] problem with rotating and translation an object in pygame

I'm having an issue where when I change the direction the character is supposed to move, I get a frame where it doesn't change direction but just translates.

So, I tried putting the rotate function before the translate one but then I encountered another problem where there is one less frame in the move, showing a stutter every time I change direction.

This is my code: main.py

from player import Player
import pygame
pygame.init()


white = (255, 255, 255)
index = 0

screen_width = 660
screen_height = 960
screen = pygame.display.set_mode((screen_width, screen_height))

image = pygame.image.load("Originalpacmaze.png")
image = pygame.transform.scale(image, (screen_width, screen_height-80))
imageRect = image.get_rect(midbottom=screen.get_rect().midbottom)

clock = pygame.time.Clock()

pacMan = Player(screen)

rect_stupid1 = pygame.Rect((175, 255), (30, 215))
rect_stupid2 = pygame.Rect((175, 450), (30, 20))
cornerTurned = False
while 1:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
raise SystemExit
if event.type == pygame.KEYDOWN:
pacMan.previousKey = pacMan.currentKey
pacMan.currentKey = event.key

if index >= len(pacMan.sprites):
index = 0
pacManSprite = pacMan.sprites[index]
pacManRect = pacMan.rects[index]

pacMan.move()
pacMan.collision(index, rect_stupid1)
if pacManRect.colliderect(rect_stupid2) and not cornerTurned:
cornerTurned = True
pacMan.nextKey = pacMan.currentKey
if pacMan.nextKey == pygame.K_LEFT:
print("IL GIANNI")
if pacMan.nextKey == pygame.K_RIGHT:
print("IL GIANNI")
if pacMan.nextKey == pygame.K_UP:
print("IL GIANNI")
if pacMan.nextKey == pygame.K_DOWN:
print("IL GIANNI")
elif cornerTurned:
pacMan.currentKey = pacMan.nextKey
pacMan.move()

screen.blit(pacManSprite, pacManRect)
pygame.draw.rect(screen, (255, 0, 0), pacManRect, 1)
pygame.draw.rect(screen, (255, 0, 0), rect_stupid1, 1)
pygame.draw.rect(screen, (0, 255, 0), rect_stupid2, 1)

index += 1
pygame.display.flip()
clock.tick(15)
