The easiest way to concatenate two lists is to use the + operator.


        
        
            
                
                
                    x = [1, 2, 3]
y = [4, 5, 6]
print(x + y)
                
            
            [1, 2, 3, 4, 5, 6]

Alternatively you can leverage the list.extend(~) method:


        
        
            
                
                
                    x = [1, 2, 3]
y = [4, 5, 6]
x.extend(y)
print(x)
                
            
            [1, 2, 3, 4, 5, 6]

In this case the original list x is modified.
