In these examples, you create a list of integer numbers and then a tuple of similar objects. In both cases, the contained objects have the same data type. So, they’re homogeneous.The elements of a list or tuple can also be of heterogeneous data types:...

Bubble sort consists of making multiple passes through a list, comparing elements one by one, and swapping adjacent items that are out of order. Implementing Bubble Sort in PythonHere’s an implementation of a bubble sort algorithm in Python:...

The algorithm works by selecting the smallest unsorted item and then swapping it with the item in the next position to be filled. The selection sort works as follows: you look through the entire array for the smallest element, once you find it you swap it (the smallest element) with the ...
