Python-Pygame moving picture when i click

Question

I'm trying to create a game. I want a picture to follow the mouse cursor but only after I click. I tried to program it but the picture only appears and than disappears again. But I want it to follow the mouse cursor until I click again. Here is a part of the code that should do it:

if mouse.get_pressed()[0]==1:
        clicked = "yes"
    if clicked=="yes":
        while 1:
            screen.blit(explosive_bootle_obr,(mouse_position))
            if mouse.get_pressed()[0]==1:
                break

And here is a full code if needed:

Answer 2

Your inner while loop seems wrong.

If you blit() but you never flip(), the screen will never be actually updated.

So remove your second while, unindent it's contents, and maybe handle the "clicked" variable differently.

EDIT: Also it will be better if you use events as described here
