function 2 inside function 1 parameters

[SheeppOSU]

I have class shop. When making the __init__ I need to give it a function within one of the parameter player. If I give it the function though, the function executes from within the parameter of the class shop, rather than executing when the shop class executes it

def openCabin(p):
    gD.fill(black)
    health = getattr(p, 'damageTaken')
    healthSub = health - (health * 2)
    p.damageTake(healthSub)
    pygame.display.update()
    time.sleep(5)

Cabin = Building(260, 30, 200, 200, Buildings[1], openCabin(p))

The function executes one line 9 where it says "openCabin"
