Looping over a simple list is nice. However, we often have an entity with more than one attribute associated with it. If you think about the vlan example in the last section, each vlan would have several unique attributes to it, such as the vlan description, the gateway IP address, and possibly others. Oftentimes, we can use a dictionary to represent the entity to incorporate multiple attributes to it.
