In this example, run_sorting_algorithm() receives the name of the algorithm and the input array that needs to be sorted. Here’s a line-by-line explanation of how it works: Line 8 imports the name of the algorithm using the magic of Python’s f-strings. This is so that timeit.repe...
Sorting in reverse (descending order) What if you want to sortfrom biggest to smallest? Thesortedfunction accepts an optionalreverseargument. When it'sTrue,it'll sort in descending order: >>>numbers=[4,2,7,1,5]>>>sorted(numbers,reverse=True)[7, 5, 4, 2, 1] ...
>>> x = {1: 2, 3: 4, 4:3, 2:1, 0:0} >>> from collections import Counter >>> #To sort in reverse order >>> Counter(x).most_common() [(3, 4), (4, 3), (1, 2), (2, 1), (0, 0)] >>> #To sort in ascending order >>> Counter(x).most_common()[::-1] ...

Write a Python program to sort a list of elements using Pancake sort. Pancake sorting is the colloquial term for the mathematical problem of sorting a disordered stack of pancakes in order of size when a spatula can be inserted at any point in the stack and used to flip all pancakes above...
() function can be used to sort the list in ascending and descending order and takes the argument reverse, which is by default false and, if passed true, then sorts the list in descending order. Furthermore, python uses the Tim-sort algorithm to sort a list, which is a combination of ...
Sorting in descending order is possible by setting reverse=True in sorted(). For non-comparable keys or values, you use default values or custom sort keys. Python dictionaries can’t be sorted in-place, so you need to create a new sorted dictionary.Read...
This example demonstrates sorting a DataFrame in descending order. descending_sort.py import polars as pl data = { 'Name': ['Alice', 'Bob', 'Charlie', 'David'], 'Age': [25, 30, 22, 35] } df = pl.DataFrame(data) sorted_df = df.sort('Age', reverse=True) print(sorted_df) ...
Worst Case: O(n^2) – This happens when every element in the input array needs to be switched during each run because it is in reverse order. Best Case: O(n) – This happens when there are no swaps required in any pass and the input array is already sorted. Still, the array must...
