Defining Singletons in Python: Simplistic and Sophisticated Approaches

While Python offers an array of methods for defining singletons, the most accepted and straightforward approach remains utilizing a module, which functions as a singleton by inherently preventing multiple instantiations. Its variables are inextricably linked to the module itself.

However, if you favor a class-based approach, be aware that Python lacks support for private classes or constructors. This implies that safeguarding against multiple instantiations solely relies on adherence to conventions within your API. Nonetheless, it's advisable to house methods within a module and regard the entire module as the singleton entity.
