pytest is a very mature testing tool for testing Python and Django based projects.

Among many built-in modules in Python one module we use frequently is datetime module. So , today I’m gonna share what I’ve learned about datetime module and how to use it.

Today I’ll talk about how to implement Queue data structure using another data structure Singly linked list in Python. If you want to know how to implement Singly linked list in Python then read this previous blog post Singly linked list.

In computer science, a linked list is a linear collection of data elements, in which linear order is not given by their physical placement in memory. Each pointing to next node by means of a pointer. It is a data structure consisting of a group of nodes which together represent a sequence. Under the simplest form, each node is composed of data and a reference (in other words, a link) to the next node in the sequence. This structure allows for efficient insertion or removal of elements from any position in the sequence during iteration.(Source: https://en.wikipedia.org/wiki/Linked_list)
