My start screen wont start when I press Run! button

So ever since i have added my Start Screen for my game and when I would press Run!/Start button it wont, the screen would just freeze up and I cant press anything. My Sit/quit works perfectly fine but my Run/Start won't

As you can see form my short demonstration, if I press Run/Start button my game will just freeze up and will stop working. I have tried rewriting my code but that still dose not work, I think I am missing something but I do not know what.

This is where I am having my problems

    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    #print(click)

        pygame.draw.rect(window, ac,(x,y,w,h))

        if click[0] == 1 and action != None:

So this is where you are starting your game right.?

    button("Run!",100,350,100,50,darkgreen,green,main_loop)
    button("Sit!",300,350,100,50,darkred,red,quitgame)

I would say not to run main loop directly like this. ok... what you want to do instead you want to change an state in relation to the event has been triggered. otherwise you will overly run the main loop since you are al ready inside a while loop. you lead this function to a function it where changes the state of a global variable like this. and let the main function run based on that global variable's state.

button("Run!",100,350,100,50,darkgreen,green,main_loop_state_turn_on)

Then proceed to evaluate it's position in relation with the buttons.

event_i = False

def main_loop_state_turn_on():
    global event_i = true

def main_loop_state_turn_off():
    global event_i = false

inside the main loop make the way to run while loop if those global variables are true.

def main_loop():
      if event_i:
         print 'Begin'
         #your code is going on here

for more understanding you can look up this
