Accessing Random Key-Value Pairs from Dictionaries in Python

Want to pick a random key-value pair from a dictionary? In Python, you can do this with ease.

Consider a dictionary:

d = {'VENEZUELA': 'CARACAS', 'CANADA': 'OTTAWA'}

To select a random item (key-value pair), simply create a list of the dictionary's items:

items = list(d.items())

Then, use random.choice() to choose an item randomly:

item = random.choice(items)

item will now be a tuple containing the random key and value:

(country, capital) = item

What if you only need the key or the value?

Choosing Random Keys:

key = random.choice(list(d.keys()))

Choosing Random Values:

value = random.choice(list(d.values()))

This optimized approach avoids creating a list of tuples.
