Can't randomly generate list with functions with random.shuffle

I'm trying to make a simple command line game in python. The only problem is that when I want to make the question randomly display, they don't. I will show you the current method I'm using to pick the functions (questions) out.

while 1:
    questionList = [Question1(), Question2(), Question3(), Question4(), Question5()]
    newList = random.shuffle(questionList)
    print(newList.pop())
    print("Checking question list\n")

I've also used random.sample and no luck with that either :/

Please help ^-^
