The **`sorted()`** function in python returns a sorted list of the iterable object i.e. *[list](https://www.educative.io/answers/what-is-a-python-list)*, *dictionary*, and *tuple.* By default, it sorts the given object in ascending order. 

In the case of strings and characters, sorting is done based on their ASCII values.

tuple = (2, -1, 7, 5)
list = sorted(tuple)
print(list)


# Algorithm used by `sorted()` 
The Python `sorted()` uses the **Timsort** algorithm which is a hybrid sorting algorithm, derived from merge sort and insertion sort.

# Syntax

```python

sorted(iterable_object, key=key, reverse=False)

```

The function has two optional attributes which can be used to specify a customized sort:

The `key` attribute requires a callable function as its input. The function will specify the sorting criteria.


touple1 = (2, -1, 7, 5)
print(sorted(touple1, reverse=True)) # Sort the list in descending order

# A callable function which returns the length of a string
def lengthKey(str):
  return len(str)

touple2 = ("London", "Paris", "Copenhagen", "Melbourne")
# Sort based on the length of the elements
print(sorted(touple2, key=lengthKey))
