It is often used to model zero or more measurements of a single variable. While it can appear like an array, a Series has an associated index that can be used to perform very efficient retrievals of values based upon labels.

Alignment is a core feature of pandas where data is multiple pandas objects that are matched by label value before any operation is performed. This allows the simple application of operations without needing to explicitly code joins.
