The singleton_package is a simple Python package that provides a Singleton metaclass. This metaclass can be used to create singleton objects, ensuring that only one instance of a class exists throughout the application.

You can install the singleton_package using pip:

pip install singleton_package

To use the Singleton metaclass in your classes, simply specify Singleton as the metaclass:

from singleton import Singleton

class MyClass(metaclass=Singleton):
    def __init__(self):
        # Your initialization code here
        pass

# Usage
instance1 = MyClass()
instance2 = MyClass()

# instance1 and instance2 will be the same object
assert instance1 is instance2
