      Pythonʼs Built-In Sorting Algorithm The Python language, like many other high-level programming languages, offers the ability to sort data out of the box using sorted(). Hereʼs an example of sorting an integer array: You can use sorted() to sort any list as long as the values inside are comparable.

Sorting primitives represent a pure sorting algo-rithm that involves partitioning the data, such as radix sort, merge sort and quicksort. Selection primitives represent a process to be executed at runtime that dynamically decide which sorting algorithm to apply.
