different choice every time random.choice

How do I make the computer compute out a different choice every time:

def quiz():
    score = 0
    qdict2 = qdict1.copy()
    for i in range(0,len(qdict2.keys())):
            rKey= random.choice(list(qdict2.keys()))
            rValue=qdict2.get(rKey)
            rKey2 = random.choice(list(qdict2.keys()))
            rValue2 = qdict2.get(rKey2)
            rKey3 = random.choice(list(qdict2.keys()))
            rValue3 = qdict2.get(rKey3)
            num = random.randint(1,3)

Thanks for any help.
