How come when I use if .collidepoint(pygame.mouse.get_pos()) and pygame.mouse.get_pressed()[0] for a button, it only stays there while I hold it?

Question

So i'm making a main menu, and when you click the button I want text to show up. I use if playbutton.collidepoint(pygame.mouse.get_pos()) and pygame.mouse.get_pressed()[0], where playbutton is the name of the button. However, when I click on the button, the text only appears while I hold onto the button, which makes sense, but is there a way to make the text stay if I only click it once? Any help would be appreciated. This is for pygame.
