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

As Charles Brunet have already said that the dictionary is random arrangement of key value pairs. But to make it really random you will be using random module. I have written a function which will shuffle all the keys and so while you are iterating through it you will be iterating randomly. You can understand more clearly by seeing the code:

def shuffle(q):
    """
    This function is for shuffling 
    the dictionary elements.
    """
    selected_keys = []
    i = 0
    while i < len(q):
        current_selection = random.choice(q.keys())
        if current_selection not in selected_keys:
            selected_keys.append(current_selection)
            i = i+1
    return selected_keys

Now when you call the function just pass the parameter(the name of the dictionary you want to shuffle) and you will get a list of keys which are shuffled. Finally you can create a loop for the length of the list and use name_of_dictionary[key] to get the value.
