# Unary Python SequenceIterator Methods

> The following unary SequenceIterator methods apply the specified operation on the object's sequence and return a sequence iterator of the same type.

> abs() | Return the sequence of absolute values of the object's elements
> neg() | Return the sequence of the negative of the object's elements

> ## Example

> Following is an example code snippet demonstrating a unary operator method:

>         cursor = con.cursor("Quote", "by_sym")
>         for quote in cursor:
>             ...
>             differenceIterator = quote.high.sub(quote.close)
>             absIterator = differenceIterator.abs()

>             ...
