如何将列表中的元素随机分配给坐标？

Question

Sumlist = ['9', '2', '7', '1', '5', '3', '4', '6', '8', '$', '$', '$', '$', '$', 'K', 'I', 'Q', 'J', 'T', 'V', 'D', 'B', 'R', 'Y', 'L', 'Z', 'U', 'P', 'A', 'W', 'C', 'O', 'G', 'M', 'H', 'S', 'N', 'E', 'X', 'F']

And let's say given some coordinates such as:

gridxy = [1,2] [1,3] [1,4] [2,2] [2,3] [2,4]

Now my question comes: How does i randomly assign the elements in my Sumlist to each of my coordinates through python? Do i use if and else statement?

I don't think I will be using tuples in this one.

Answer 1

You should use the random module to randomly sample your Sumlist and associate each element to the element in gridxy using the zip builtin function :

Tested on Python 2.7.9

>>> import random
>>> Sumlist = ['9', '2', '7', '1', '5', '3', '4', '6', '8', '$', '$', '$', '$', '$', 'K', 'I', 'Q', 'J', 'T', 'V', 'D', 'B', 'R', 'Y', 'L', 'Z', 'U', 'P', 'A', 'W', 'C', 'O', 'G', 'M', 'H', 'S', 'N', 'E', 'X', 'F']
>>> gridxy = [[1,2],[1,3],[1,4],[2,2],[2,3],[2,4]]
>>> random.seed()
>>> zip(gridxy, random.sample(Sumlist, len(gridxy)))
[([1, 2], '$'), ([1, 3], '1'), ([1, 4], '6'), ([2, 2], 'X'), ([2, 3], '$'), ([2, 4], '$')]
