not allowing me to input and loop

[Gus1]

def quiz():
    for count in range(1):
        import time
        print ("hello and welcome to my input output quiz")
        time.sleep(2)
        print()
        print("INTRUCTIONS")
        time.sleep(2)
        print()
        print(" you will a choice of 4 possible answers to chose from")
        print("you will have 20 second to choose.please answer in lower case")
        start =input("Are you ready to start Y/N :  ")
        if start == "y":
            print("QUESTION 1")
            print()
            Q1=input("which one of these is NOT an import device ? ")
        if Q1 == "B" or Q1 == "b":
                print ("correct, next question")
        else:
                    print("incorrect, please try again")
                    # loop before question ? how ever you do that?
                    print()
                    time.sleep(2)
                    print("A: keyboard")
                    ()
                    print("B: usb")
                    ()
                    print("C: Mouse")
                    ()
                    print("D: Joystick")
                    ()
                    time.sleep(20)
                    if count == 0:
                        print ("times up, please try again")
                        # loop

Your import statement should be at the top of the file. To loop until the question is answered, try something like this:

>>> while True:
... 	s = raw_input("Input 'X'")
... 	if s.lower() == "x":
... 		break
... 	print "Wrong! Try again"
... 	
Wrong! Try again
>>>

You have to call your function as in:

quiz()

You don't ever change "count" so this statement will execute every time

                   if count == 0:
                        print ("times up, please try again")

You perhaps want something more like

if number_of_tries > maximum_allowed:
    return False  ## exit the function

And we usually say input device in the US but it may be different where you are.

 Q1=input("which one of these is NOT an import device ? ")
