This means that we do not have to strictly follow set design patterns for all of our code, but analyze our needs and apply the best-suited design pattern for our needs.Design patterns arise from a wealth of experience in solving problems in software development and are tried and tested to fit particular scenarios.

The intent of singleton design pattern is to have only one instance of a class and it should be accessible to multiple clients through well defined access point. Any attempts to create another government are forbidden.We can implement this government analogy in a singleton class as follows in Python:In our example, we define the variable that will hold the single object to be instantiated.
These aspects might not remain the same for all software out there but will hold true for a lot of scenarios. This article describes the main strategies to implement the Singleton design pattern in Python. It is up to you the developer to decide which one is more suitable to your case.Billal Begueradj
While some others consider it just a special singleton implementation. In this article, we'll be diving into the Singleton Design Pattern, implemented in Python. This allows the creation of as many instances as needed, but any of these instances which modifies the state mirrors the modification to all the remaining instances.
