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.
