Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...
print("Sorted list (ascending order):", input_list) Output: Explanation: Here, the user enters numbers with spaces between them. The program sorts these numbers in ascending order using the for loop and displays the sorted list. Descending Order Now let’s sort a list in descending order us...
To sort a list of strings in alphabetical order in Python, you can use the sort method on the list. This method will sort the list in place, meaning that
Therefore, the third elements of all the strings are compared, and the elements in the list are sorted in either ascending order or descending order (if reverse is set to True).Open Compiler def func(key): return key[2] aList = ['123', 'xyz', 'zara', 'abc', 'xyz'] aList.sort...

In the next section, we’ll discuss this key parameter more deeply.Sort a List of Strings in Python Using the Sorted FunctionWhile lists have their own sort functionality, Python exposes the sort functionality with a separate function called sorted which accepts an iterable. In other words, ...
