# Python program for implementation of MergeSort def mergeSort(arr): if len(arr) >1...
Write a Python program to sort a list of elements using the merge sort algorithm. Note: According to Wikipedia "Merge sort (also commonly spelled mergesort) is an O (n log n) comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the implementation pr...
Abstract base classes provide a blueprint for concrete classes. They don't contain implementation. Instead, they provide an interface and make sure that derived concrete classes are properly implemented. Abstract base classes cannot be instantiated. Mutable default parameter If python function default in...
The implementation of all function is equivalent to def all(iterable): for element in iterable: if not element: return False return True all([]) returns True since the iterable is empty. all([[]]) returns False because the passed array has one element, [], and in python, an empty ...

Python has its own implementation of sort() function, and another is sorted() function where sort() will sort list whereas, the sorted function will return new sorted list from an iterable. The list.sort() function can be used to sort the list in ascending and descending order and takes ...
Here is a portion of a program I wrote for my own needs that will only update records in the update table when they do not match the source table. The dictionary built in this example trims white-space characters from the source table, since the update table has no white-space...
In my earlier post on the Python code for Quick Sort, my implementation takes the first element of the unsorted array as the pivot element. However with some mathematical analysis it can be seen that such an implementation is O(n2) in complexity while if a pivot is randomly chosen, the ...
