Iterator and Increment - David-Lennuk/Buketov_Python GitHub Wiki

Iterator

In computer programming, an iterator is an object that progressively provides access to each item of a collection, in order. A collection may provide multiple iterators via its interface that provide items in different orders, such as forwards and backwards. An iterator is often implemented in terms of the structure underlying a collection implementation and is often tightly coupled to the collection to enable the operational semantics of the iterator. An iterator is behaviorally similar to a database cursor.

Increment

Increment refers to the act of increasing a value or quantity by a specific amount. In the context of technology, computing, programming, and communications, increment is often used to describe the process of adding or increasing a value by a predetermined step or unit.
