python - Python：从两个不同的列表中获取几个值

Question

Python 是否有一个内置方法，我可以以随机方式从两个不同的列表中获取几个值？

前任：

listOne = ['Blue', 'Red', 'Green']
listTwo = [1, 2, 3]

# I want to get the result:
# ('Blue',3),('Red',2),('Green',1)
# or ('Blue',2),('Red',3),('Green',1)
# or ('Blue',1),('Red',2),('Green',3)
# and so on...how can I use a method get this result in a random way?

Answer 1

如果你想要一个随机配对，你可以使用random.shuffle()：

>>> import random
>>> listOne = ['Blue', 'Red', 'Green']
>>> listTwo = [1, 2, 3]
>>> random.shuffle(listTwo)
>>> zip(listOne, listTwo)
[('Blue', 3), ('Red', 2), ('Green', 1)]
>>> random.shuffle(listTwo)
>>> zip(listOne, listTwo)
[('Blue', 2), ('Red', 1), ('Green', 3)]

Answer 2

您可以使用它random.choice来执行此操作：

listOne = ['Blue', 'Red', 'Green']
listTwo = [1, 2, 3]

import random
print (random.choice(listOne), random.choice(listTwo))

Answer 3

>>> from random import choice
>>> listOne = ['Blue', 'Red', 'Green']
>>> listTwo = [1, 2, 3]
>>> map(choice, (listOne, listTwo))
['Green', 1]
