How to iterate through dict in random order in Python?

Question

How can I iterate through all items of a dictionary in a random order? I mean something random.shuffle, but for a dictionary.

Answer 1

I wanted a quick way for stepping through a shuffled list, so I wrote a generator:

def shuffled(lis):
    for index in random.sample(range(len(lis)), len(lis)):
        yield lis[index]

Now I can step through my dictionary d like so:

for item in shuffled(list(d.values())):
    print(item)

or if you want to skip creating a new function, here is a 2-liner:

for item in random.sample(list(d.values()), len(d)):
    print(item)
