python - 在 Python 中随机改组字典

Question

好吧，问题是，我需要在 python 中使用字典，但我意识到我不能随机地对它们进行洗牌。我必须随机洗牌，并将值分配给同一个字典。任何帮助，将不胜感激。

你不能重新整理字典。您可以做的是创建一个字典键的列表并对其进行洗牌，以实现访问字典内容的新任意顺序:

>>> import random
>>> d = {1:2, 3:4, 5:6, 7:8, 9:10}
>>> d
{1: 2, 3: 4, 9: 10, 5: 6, 7: 8}
>>> keys =  list(d.keys())      # Python 3; use keys = d.keys() in Python 2
>>> random.shuffle(keys)
>>> [(key, d[key]) for key in keys]
[(1, 2), (5, 6), (7, 8), (9, 10), (3, 4)]
>>> random.shuffle(keys)
>>> [(key, d[key]) for key in keys]
[(9, 10), (3, 4), (1, 2), (7, 8), (5, 6)]
>>> random.shuffle(keys)
>>> [(key, d[key]) for key in keys]
[(1, 2), (7, 8), (3, 4), (5, 6), (9, 10)]
