shuffle dictionary values in python

Question

I have a dictionary and I want to shuffle the values, not the keys. For example:

{"a": "ACAT", "b": "ACTG", "c": "ACCC"}

and after shuffle:

{"a": "ACAT", "b": "ACTG", "c": "ACCC"}

but I don't know how I can do this work in python. I will be grateful if you help me.

Answer 1

The random module has a function that shuffles in-place.

So we can get the dict's values, shuffle them, and construct a new dict.

Demo:

>>> import random
>>> d = {
...     "a": "ACAT",
...     "b": "ACTG",
...     "c": "ACCC"
... }
>>> shuffled = list(d.values())
>>> random.shuffle(shuffled)
>>> dict(zip(d, shuffled))
{'a': 'ACCC', 'b': 'ACTG', 'c': 'ACAT'}
