How to make two simultaneous actions on an object?

Question

Python

I have an object, I can move it, and when I press the spacebar, another object appears and flies up, but as soon as I press the spacebar, the main object stops and I need to press the movement keys again to move it.
Is it possible to somehow make the object not stop after pressing the spacebar, and the second object also starts moving. Here is the event definition code:

for ev in pygame.event.get():
       
        if ev.type == pygame.QUIT:
            main_while = False
        
        if ev.type == pygame.KEYDOWN:
            if ev.key == pygame.K_RIGHT:
                if hero.x < 420:
                    hero.x += 0.5
            if ev.key == pygame.K_LEFT:
                if hero.x > 3:
                    hero.x -= 0.5
            if ev.key == pygame.K_SPACE:
                if not bul_push:
                    bullet.x = hero.x + 30
                    bullet.y = hero.y + 10
                    bul_push = True

Thank you in advance

General approach: by pressing the key, do not change the position, but the speed of the object ( += vel). And when they release the key, change it back (-= vel).
