Looping through key-value pairs in a dictionary in Python

We can loop through a dictionary using a combination of for loops and the items(~) method.

NOTE

The items(~) method simply returns a list of tuples that contain each key-value pair, which we are then able to loop through using a for loop.

Example

Consider the dictionary below:

d1 = {"A": 1, "B": 2, "C": 3}

To loop through the key-value pairs:

for key, value in d1.items():
print("Key:", key)
print("Value:", value)
print('\n')
Key: A
Value: 1
Key: B
Value: 2
Key: C
Value: 3

The key, value in the above example are temporary variables being used, hence they can be named however you like and they would still serve their purpose.
