I can't move an image with pygame

Question

import pygame
import sys
pygame.init()
weight=550
height=400
screen = pygame.display.set_mode((weight,height))
image=pygame.image.load("Capture.jpg").convert()
ix= 70
iy = 80
speed =10
imageplace = screen.blit(image,(ix,iy))
pygame.display.update()
running=True
while running:
    for event in pygame.event.get():
        pygame.time.delay(10)
        if event.type == pygame.QUIT:
            running=False
        keys=pygame.key.get_pressed()
        if event.type == pygame.MOUSEBUTTONDOWN:
            pos = pygame.mouse.get_pos()
            pos_x = pos[0]
            pos_y = pos[1]
            if (keys[pygame.K_LEFT] or keys[pygame.K_a]) and ix > 0:
                ix-=speed
            if (keys[pygame.K_RIGHT] or keys[pygame.K_d]) and ix > 0:
                ix+=speed
            if (keys[pygame.K_UP] or keys[pygame.K_w]) and ix > 0:
                iy-=speed
    
            if (keys[pygame.K_DOWN] or keys[pygame.K_s]) and ix > 0:
                iy+=speed
            
            
            if imageplace.collidepoint(pos_x,pos_y):
                print("You have clicked on button")
            else:
                print("Wrong Direction")

I tried to move an image with pygame but it didn't work. I am new at this. I couldn't find anything on internet and I didn't understand it.

Your main loop (`while running`) does not do any graphical update. It should at least contain one `screen.blit(something)` to draw a surface on the screen and `pygame.display.update()` to update the display. — qouify, Mar 12 '22 at 12:52

See How can I make a sprite move when key is held down and you must redraw the scene in ever frame. The typical PyGame application loop has to:

limit the frames per second to limit CPU usage with pygame.time.Clock.tick
handle the events by calling either pygame.event.pump() or pygame.event.get().
update the game states and positions of objects dependent on the input events and time (respectively frames)
clear the entire display or draw the background
draw the entire scene (blit all the objects)
update the display by calling either pygame.display.update() or pygame.display.flip()

Example based on your code:

import pygame

pygame.init()
width, height = 550, 400
screen = pygame.display.set_mode((width, height))
clock = pygame.time.Clock()
image = pygame.image.load("Capture.jpg").convert()
imageplace = image.get_rect(topleft = (70, 80))
speed = 5

running=True
while running:
    clock.tick(100)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running=False
        if event.type == pygame.MOUSEBUTTONDOWN:
            if imageplace.collidepoint(event.pos):
                print("You have clicked on button")
            else:
                print("Wrong Direction")

    keys = pygame.key.get_pressed()        
    if (keys[pygame.K_LEFT] or keys[pygame.K_a]) and imageplace.left > 0:
        imageplace.x -= speed
    if (keys[pygame.K_RIGHT] or keys[pygame.K_d]) and imageplace.right < width:
        imageplace.x += speed
    if (keys[pygame.K_UP] or keys[pygame.K_w]) and imageplace.top > 0:
        imageplace.y -= speed
    if (keys[pygame.K_DOWN] or keys[pygame.K_s]) and imageplace.bottom < height:
        imageplace.y += speed

    screen.fill((0, 0, 0))
    screen.blit(image, imageplace)
    pygame.display.update()

pygame.quit()
