Snake Game question

Question

Hi Everyone,
Would someone be able to look at my code below and tell me had I can get the snake image to turn 90 degrees instead of 45 degrees when moving? I think I have to stop it from moving before it turns but I can't figure out how to do that.
Appreciate any help.
Thank you!

import pygame

pygame.init()

#create the screen
screen = pygame.display.set_mode((800, 600))

# Tile and Icon
pygame.display.set_caption("Snake Game")
#icon = pygame.image.load('snake.png')
#pygame.display.set_icon(icon)

# snake Head
snakeImg = pygame.image.load('snakeHead.png')
snakeImgX = 400
snakeImgY = 300
snakeImgX_change = 0
snakeImgY_change = 0

#Apple
appleImg = pygame.image.load('apple.png')
appleX = 370
appleY = 480

# score
#font = pygame.font.SysFont("comicsansms", 72)
#score = font.render("Hello, World", True, (0,128, 0))

def apple():
screen.blit(appleImg, (appleX, appleY))

def snake():
screen.blit(snakeImg, (snakeImgX, snakeImgY))

# Game loop
running = True
while running:
#RGB - Red, Green, Blue
screen.fill((0, 150, 0))

for event in pygame.event.get():
# Moving Snake
# if keystroke is pressed, check if its up, down, left, or right

if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
snakeImgX_change = -2
print("Left arrow if pressed")

if event.key == pygame.K_RIGHT:
snakeImgX_change = 2
print("Right arroq is pressed")

if event.key == pygame.K_UP:
snakeImgY_change = -2
print("Up arrow is pressed")

if event.key == pygame.K_DOWN:
snakeImgY_change = 2
print("Down arrow is pressed")

if event.type == pygame.QUIT:
running = False

snakeImgX += snakeImgX_change
snakeImgY += snakeImgY_change

if snakeImgX <=0:
snakeImgX = 770
elif snakeImgX >= 770:

Answer 1

The Cobra should move either in X direction or in Y direction. This means you must switch on the corresponding movement and switch off the other one at the same time.
For example:

if up:
snakeImgY_change = -2
snakeImgX_change = 0
