sorting – What algorithm does pythons sorted() use?

Python uses an algorithm called Timsort:

Timsort is a hybrid sorting algorithm, derived from merge sort and
insertion sort, designed to perform well on many kinds of real-world
data. It was invented by Tim Peters in 2002 for use in the Python
programming language. The algorithm finds subsets of the data that are
already ordered, and uses the subsets to sort the data more
efficiently. This is done by merging an identified subset, called a
run, with existing runs until certain criteria are fulfilled. Timsort
has been Pythons standard sorting algorithm since version 2.3. It is
now also used to sort arrays in Java SE 7, and on the Android
platform.

The sort algorithm is called Timsort. See timsort
