"action_input": "To implement a Singleton class in Python, you can define a class with a private constructor, a class variable to store the instance and a static method to get the instance. Here's an example:\n\n```python\nclass Singleton:\n __instance = None\n\n def __init__(self):\n if Singleton.__instance != None:\n raise Exception('You cannot create more than one instance of Singleton class.')\n else:\n Singleton.__instance = self\n\n @staticmethod \n def getInstance():\n if Singleton.__instance == None:\n Singleton()\n return Singleton.__instance\n```"
