如何在随机化一个列表的情况下并行遍历两个列表

Question

This thread 解释了如何遍历两个并行列表。

但是，当我将该课程应用到打乱后的列表时，出现以下错误："zip argument #2 does not support iteration."为什么打乱后的列表不支持迭代？我还能如何随机化答案选择的顺序？

import random

def answers():
    answerList = random.shuffle([answer1, answer2, answer3, correct])
    numberList = ["1: ", "2: ", "3: ", "4: "]
    for x,y in zip(numberList,answerList):
        print x,y 

prompt = "What is the average migrating speed of a laden swallow?"
answer1 = "Gas or electric?"
answer2 = "Metric or English?"
answer3 = "Paper or plastic?"
correct = "African or European?"

print prompt
answers()

Answer 1

random.shuffle 随机到位。按如下操作：

answerList = [answer1, answer2, answer3, correct]
random.shuffle(answerList)

Answer 2

感谢 pacholik 提供解决方案。

import random

def answers():
    answerList = [answer1, answer2, answer3, correct]
    random.shuffle(answerList)
    numberList = ["1: ", "2: ", "3: ", "4: "]
    for x,y in zip(numberList,answerList):
        print x,y 

prompt = "What is the average migrating speed of a laden swallow?"
answer1 = "Gas or electric?"
answer2 = "Metric or English?"
answer3 = "Paper or plastic?"
correct = "African or European?"

print prompt
answers()
